Please answer multiple options to which relates.

Im just curious after reading an article.

Please add a reply or PM me if you have any particular thoughts.

PS) Yeah I know I am shite at putting together a poll that results would mean anything!

i expect that "line mod" is "WLO-toogles",and not the 5th line mod i had on my fox

Nah mate - its the Slider down line mod - where the control line does not go through the keeper rings or slider.

………. In addition, if you vote for “I don’t use the line mod slider down / off” can you please also PM me.

Thanks

Or just post here. I'd love to hear the reasoning behind this.

-> Cue Outrager with a long discourse on time spent switching toggles vs. time spent in hospital, and why there is a lifetime time savings from just taking the injuries.

The Line Release Modification (LRM) , or Line Mod, is a technique developed by Mark Hewitt to allow the clearing of a line over on a slider down BASE jump. I understand that it was originally conceived while in the hospital, after having spun in under a line over.

Basically, the Line Mod is just routing the control lines outside both the slider grommets and the keeper rings (the metal rings on the risers). So, if you drop (or toss) a toggle, it just flies away behind you (or wherever), releasing the tension on a line over.

It should be noted that this technique is not for use on a slider up jump because a premature brake fire could result in a toggle/slider entanglement, followed quickly by high speed impact under a snivelling canopy, usually resulting in a ride in the white bus with the flashing lights (or worse, the long black station wagon).

After reading Faber's response, I want to reiterate for people reading this discussion:

The Line Release Mod is the industry standard for slider down BASE. You should always use it unless you are absolutely certain that you know better.

I have talked to three or four respected, experienced jumpers who don't use it. All of them stopped using it after they had many, many (think, 500+) jumps. Unless you are in this experience category, please use the line mod.

I received an email from a very experienced jumper shortly after this thread began which read:

There is nobody that actually jumps ( Slider Down ) with the brake lines routed thru the Slider Grommet & keeper Ring.....Is there ??????

There can't be people out there that do that.

This pretty much sums up the feelings of the vast majority of experienced jumpers.

I think also, some of those who might not use it, might use WLO toggles, with one setup for all jumps. Having never had a line over, but jumped the WLO, I think the normal toggles is better and faster, in case you would get a line over. Also, as you have mentioned, the simpler in base, the better. It took me a while to make full use of the concept.

Wrong. WLO toggles (which I used until few months ago, when it happened an event after which I stopped jumping WLO system) can be used in any jump, slider off and slider up, but their use for releasing the offending control line is meant only when jumping slider up. In case of a line over in a slider off jump, the fastest and cleanest way to get rid of line over still is to discard the offending toggle.
This is obviously the wat to go, and I clearly remember a post on the BB by Jimmy (by Vertigo) stating exactly this: "in a slider off jump, in case of line over, the way to go is to rapidly discard the offending (WLO) toggle; release of offending line in case of line over using the release mechanism of WLO toggle is meant to be performed uniquely when jumping slider up."
The main reason to discard the toggle, in case of line over in a slider off jump (and NOT to get the WLO release mechanism to be effected), is that this way it is the fastest and smartest way to solve the problem.
Just my 0.02€
P.S.: All the above is under the obvious assumption that when you jump slider up you route the control lines inside the slider grommet and inside the ring on the riser, and when jumping slider off you use the line mod, i.e. you route the control lines (outside slider grommet and) outside the ring on the riser, using the white loop on riser for setting up the brake. I honestly cannot see which are the advantages (when jumping slider off) to route the control lines inside ring on riser, while I see only disadvantages doing so...

Stay safe out there

It is interesting to see most people unable to see the advantage of jumping slider down without the LRM. - But I just wanted to question this myself. Sorry if this seems obvious and very fucking stupid.

The reason I posted this poll was to guage what people were doing and what their feelings about this were. I have received several calls from people thinking I was going to start jumping this way - this was not my intention. My intention was to get myself to question the LRM and its intention and then the intention of all related aspects.

There is no getting away with the fact that people are jumping slider down without the LRM. Their choice seems to be something that I can understand. But is also something I am questioning.

Some of my thoughts are: (and I am well aware that some of this maybe complete shit - but I would appreciate correction on my thoughts)

The LRM was developed in a time when people were jumping skydiving equipment and they were jumping with the control lines in the slider grommets and keeper rings. MH (whilst in hospital) thought of a way to "cure" a line over which is even more possible jumping slider off or down then slider up. This was an inovation and moved slider down jumping along. Other problems were discovered - one was tail inversion - which to my belief is still questioned on whether is a cause of lineovers. This caused its own problems - the Tailgate was developed to prevent Tail Inversion (and not lineovers as many people are led to beleive) - but inadvertently also prevented lineovers. Since the Tailgate and prgression with packing lineovers slider down have become rare, both the tailgate being a prevention of tail inversion and lineovers and the LRM being a cure of lineovers - slider down / off jumping has become less of a gamble.

With the Tailgate has the LRM become "not needed?" - how many people have used the LRM in anger to clear a lineover? Do you know anyone that has? With the advent of vented canopies and more knowledge on lower end freefalls / Low SL / Low PCA / Tards / McConkey etc then is a LRM truely something that people will be able to use opening so low? The vented canopy was there to make lower openings safer but i beleive that it just meant that people took them lower.

The other aspect is the fact that brakes fire on opening and / or people drop toggles.

Without a LRM this does not become a pain in the arse that it is - not that it should be a real pain, just an inconvienience.

I dont really know what I am trying to answer in looking into this - but I would say that I am not about to jump without the LRM - but I am just questioning the whys and wherefores........ thats all.........

The experienced of you may have seen this time and time again - but I like to question what and why I am doing something.

Flame the new guy if you so wish - but I thought I would throw my thoughts out in the public to help me progress my anorak status further!.............

Many thanks.

Michael


Edit: to add I am shite at writing down what I am thinking - so please be aware it may not come across as I want. Thats just me!
