pulling slider down

[johnny1488 1]

Does anyone fly a moderatly loaded canopy (over 1.2:1) and pull the slider down to the rings. I know it creates less drag and lets the lines spread out more. Does it make any noticable difference in flight or landing? I have 2" risers right now so pulling it down isnt to convienient. I was thinking of switching to 1". I'd like to get every bit of performance out of my safire209.

Just a guess but I don't think pulling it down is quite as important as having it collapseable.

You're kinda right Clay... kinda...
Pulling ot down wont reduce drag that much more then just collapsing it.
However, what pulling it down does is lets the canopy flatten out more when you loosen the chest strap. This in turn gives a more efficient wing.

It's really not too much of a pain in the ass to pull a slider down over 2-inch risers, so long as you don't have big, huge covers on your rapide links. In the case of your very-large (by my standards) Safire, you will not be doing so much to allow the wing to flatten as getting that noisy slider out from over your head.

If you switch to triple risers your canopy will flatten out and you should see improvement in your surf.

Actually, Chuck brought up some good points on triple risers last week. Look at the archives and you'll notice that on a rear riser surf, you pay for distance with triple risers....

Chuck, I did not fully understand what you were trying to say about the triple risers deflecting the tail without input. Can you clarify that for me?

As it is now i do collapse it and loosen my chest strap. Im lot looking to surf, just the best flight characteristics. Do the triple risers bring with them any inherant problems? I just dont want to pull the slider over the 2" only to see it wont go down all the way and cause some sort of problem. Thanx for the input everyone.

the only thing that is a pain in the but about pulling it down is if you done have toggle keepers that the toggles go into, the slider will sometimes catch on the toggles. All you have to do in that case is point the head of the toggle through the Groment in the slider on each side manually.then a quick tug, and its cleared.

Here is what my rigger told me / Why I pull my slider down.
The slider can and will wear your lines out where they attach to the risers. Vectran lines wear out relatively fast as it is, and with that slider flapping at the top of the risers, they will wear out even faster. Even with it collapsed it still moves around. Also this is another place for your steering lines to rub against causing more wear on them. He did tell me about the performance benefits, such as flattening out the canopy, reducing drag, and such, but I do it to prevent wear and tear on my rig, and it only takes an extra second after collapsing it to pull it down behind my head.

What Chuck said...
but also (freefly so my chest strap is tight)..loosen your chest strap as much as you can, then pull slider down and your risers will be allowed to spread out and flatten the canopy even more.
Even if you are not loaded at 1.9 this can help you get back from a long spot. slider behind head (less drag), canopy flattend doe to spread chest strap and slider at bottom of risers. pull your legs up too for less frontal drag.
Make it a habit.
more scientific theory...
also if you are loading a canopy up more... some of the tiny canopies have shorter lines..., by spreading your risers as far as possible, you lower attachment fulcrum (center of gravity of the suspended weight...you) on your body a little bit (you are a pendulum under the canopy),,if the attachments points are spread more at your container, you will be more stable if you are doing hard toggle turns and thus ... maybe in 2 cases out of 10 prevent self induced line twists
does that make sense?

Actually, with trips you are NOT deflecting the whole back half of the parachute with toggle input; only the tail, as the brake lines do not run through guide rings on the back risers.
The theory PRO triples is that the majority of the airfoil remains intact and therefore more efficient, which leads to a longer surf. The CONS are that if you have a premature brake release it is a complete motherfucker to get your slider down past the toggles and all three sets of risers without augering yourself. If you are unsuccessful, then you get stuck landing with your slider up; this is not the hot ticket under a main loaded at 2.6:1. The other CON, though only if you are dead-on dialed-in, is that the very best swoopers in the world do not use triples now. They have found that with LOTS of practice, they get longer swoops by rear-risering. Having triples and rear risering is non-productive. As as staunch supporter of triple risers for the past decade, I am now probably going to change back to standard risers for the proven benefit in the competitive arena.

Also, to the original poster: We collapse and pull down our slider because most of us are terribly put off by Slida Flappida, a disease only you can cure.
