But of course. Parachuting is not safe. Every component , every action has a risk associated with it. I have heard people swear off Vectors because they felt that meshless reserve PCs were black death. I have heard people want nothing but Racers because they offer the most superior pin protection. Some people have said that non-breakaway ringsites are suicidal. Early mini risers broke, so the integrity risers were created - and they hungup. BASE jumpers eliminated the slider for faster and more consistent openings and in return lineovers followed. Rapide links are weaker than slinks, but the slinks are much more susceptible to abrasion. Every component has risks associated with it. I can bring up many more examples, but the bottom line is that if you want the absolute safety, you need to stop jumping outta them planes.

There was a method to allow your lines to open up long before there where mini risers. It’s called a split slider. You get the added performance while maintaining the original 3 ring system design. But I guess it is not viewed as “cool”. Sparky and way before Bill Booth was even considering a career in parachutes there was already a method for cutting away a main canopy. But the 3rings work better and faster and are less prone to malfunction than the Capewells, R3s, etc. Split sliders are great. Unless you misrig them unless you don't watch for the wear unless you are rushing to make the next load and of course - unless you don't care about fashion :)

to add another datapoint - I just packed a 2001 Mirage G3 M6 with a PDR176. The main is a 200 jump Triathlon 190 and it fits well, but not too loose. I feel that a ZP 170 will work well.

Seriously ? an IDENTICAL thread is just a few lines down from yours. http://www.dropzone.com/cgi-bin/forum/gforum.cgi?post=3798472

So, have a hand deploy reserve do ya? no, I have a ripcord activated reserve. but unlike jumpers of many years past it's located on my back instead of my chest. things change.

Another correction - Better performance that comes with additional risk. Please do elaborate. How does letting your wing flatten out due to riser ends being spread more increase the risk ?

But experimentation often also kills. Therefore, it should be done thoughtfully and with all due caution. I agree. For example, just because someone has been happy jumping a spring loaded main PC for 30+ years, it does not mean that it's the best tool for the job. Since we have 20+ years of throwout experience in the market, going to a BOC/ROL would be a safe choice. Neither one is a bad choice.

Very true, so I'll stand a little corrected, thanks. However, I have slider stops to prevent my slider from coming down over the risers. Like many others, I simply use a collapsible slider and leave it above the toggles. I'm into simplicity and safety, not high performance.

Not as strong as type 8 (the wide ones) risers. The only problem with those was style. It's also well known that the large three rings are more reliable than the mini rings, but better quality control has narrowed that gap. I admit I gave in to the fashion police and got mini rings and skinny risers on my current rig, so I can't really talk. let's not forget about practicality of mini risers where they allow you to pull the slider all the way down and allowing the lines to spread out allowing the canopy to fly better. Hardly a fashion statement, don't you think ?

not to sound like a smartass, but why not call the phone number on the patch :) ?

it is. but it's not a support group or a help forum for lazy people.

the reason is very simple. Assuming you are PRO packing. once you put the D lines in the center, the rest of the canopy covers up the C/B/A. Once you work your way back to the As, you will need to go back and pull the B/C/D sets back into the center, thus forcing yourself to do extra work. Keep in mind - it's how the packjob looks at the end, not how you got there what makes the difference. If you spent 20 minutes mindfucking yourself and used a fucked up super uncomfortable way to get the lines in the center and the material to the outside, you just achieved the same that an experienced packer will do in 5 mins. The end result is the same, but you spent 4x the time doing it :) On the final note - Please drop the attitude of "if it works, lets not change it" - innovation is the reason we are jumping F111 square reserves mounted on our backs, though twill unsteerable cotton rounds worked (most of the time). Or don't listen to any advice that you don't like , it's a free world.

what, too lazy to google ?

Waht is nitpicking ? What is JFGI ? What do you call a person who is very annoying ?

A real funny one. Read what he is replying to.

How about : Persuasive precedent google it.

I know in the Protrack it will not record speed unless you are in freefall for over 20 seconds. I am guessing it's similar with the Viso. Think about how the speed is done - it's averaged from the time you leave the airplane (very little vertical speed, mostly bleeding off the forward movement of the plane), to the time you deploy, at which point you are going at or close to terminal. If you do a 4 second delay your average speed will be very inaccurate relative to the speed you were deploying at.

I think what is keeping jumpshack alive more than anything is JCO metals there company that builds handles, ripcords and pins. They supply most of the industry with them. Their military contracts probably help as well. Really once John Sherman retires the company will probably start to do a lot better. I have never met him personally but met pretty much everyone else there. My impression is that he really controls how some of the things are because he designed it and doesn't want it to be changed or it is of the nature that he tells people what they need and want. If they acted more like other companies where they listened more to the customer and gave them a product they asked for I feel they would do better. After all that is why some of the companies have grown to the size they have. and I agree 150% with you ! Jumpshack gives me an impression of a stubborn, and extremely unwilling to change company. From talking to many of the people who have been around much longer then me, and having come from an all-Racer dropzone I have seen and worked with plenty of gear to back up what I say. To me, the magnetic riser covers are about the only useful feature that Jumpshack has. whoever mentioned brand wars may not realize that I have jumped ALL the containers that have passed through me (that I could fit into :), which is to say pretty much all the even mildly popular stuff in the US for the last 20 years - so I say what I say based on a fair bit of first hand experience rather than on having owned a single brand and sticking with it.

I am sorry formerjumper, but you sound like you are trying to find a generic resource to dig up information for the benefit of a SUING as a result much more recent injury. Please state your name (so we can find your injury), and name the sport parachute club where the accident occurred. I smell an attorney/paralegal doing their research to try to shutdown yet another DZ.

Read more into it. low market penetration=low sales=less profit=less $$$ for development & redesign I can stretch that chain of deductions into being unsafe, but that obviously is a stretch. many new riggers don't know how to pack a Racer or how to pack it well. The recent tandem double fatality occurred because of a misrouted RSL. Of course you can argue that it was the riggers fault - and I would have to agree. However, when the system is build so different from what's the "standard" - it's hard to be current on it, and humans will always make mistakes. Wasn't it Jumpshack that in the late 80s/early 90s insisted on having a 4ft main bridle ?

at the cost of an extremely low market penetration. Personally, they way I see it, once the "old school" jumpers stop jumping , Jumpshack will run out of customers :( (for the purpose of this thread, lets define old school as consisting of mostly four digit USPA D-numbers and foreign equivalents)

both the Spectres I packed in there had over 800 jumps

I never use packers, and I believe myself to be pretty proficient at packing. I am giving you factual information based on two seasons of packing that particular rig.

What exactly scared her ? I find that many people are scared because of their lack of knowledge. And with some of them, once the mechanics of the sport are explained, the fear subsides. "I don't want you to do ****" is an extremely selfish statement to make if it's based on emotion.

I have an RSK1 with an Optimum126. Packing a microlined Spectre120 is ok, and it fits firm. a dacron lined Spectre 120 is really right.
