Re: [GreenMachine] Slider down
I can't believe GreenMachine was the first and only person to (notice)mention that you are talking about doing a slider down base jump with your control lines routed through the slider. What break setting were you planning on using?
Jessica Klutmier can tell you that's not a good idea. I'd probably be jumping the space needle once a year if that hadn't jacked her up on a publicized space needle jump. Line over spun her into the grass and broke her back. If her control lines were outside the slider she probably could have dumped the toggle and been alright.
I agree with leaving the slider on in case of a single 3 ring failure. Obviously you should check your shit before you plan on jumping off of something and trusting your life to it, but who knows if some final destination shit happened and somehow your cutaway line worked its way out on one side. Plus it's easier to switch back and forth and lessens the chance of you fucking up your own rigging when taking it on and off.
Back to break settings. I don't have a ton of parachuting or rigging experience, so if there's more insight available hopefully people say something, but I think of my "deep" break setting as my slider down break setting and my "shallow" break setting as my slider up break setting.
For slider down, you want it as deep as you can get without stall. That way your forward speed is as slow as possible on opening. Writing this makes me think about how break setting could effect the speed of pressurization, hopefully somebody with more experience can comment on that.
For slider up you want it deep enough to shove the slider down without being to deep and stalling, and also keeping the forward speed as slow as possible. Hopefully people can comment on how shallow versus deep effects speed of slider decention.
As far as I know, most if not all base canopy's with manufacturer set break settings, if you used the deep break setting with the control lines routed through the slider the canopy would be in a stall until you popped the toggles and eased up a bit, or surged out.
