Re: [rfarris] opening shock
I have a bum shoulder, ok I have two bum shoulders but my left is much worse - most of the rotator cuff assembly is torn entirely off the bone. I was told two years ago "don't do anything physically demanding, schedule surgery at once, take it easy in the meantime, and get ready for 6+ months of rehab." Of course, I ignored that.
I've dislocated that shoulder twice during deployment, both slider-down. That is not fun; both delays were in the 3-3.5 range. After those incidents, I learned to basically cross my arms after tossing the PC to hold my shoulder in during opening shock. Not very stylish, but it works.
BASE deployments slider-down in the 3 - 4.5 range (particularly above 4) can be very, very punishing. I've had partial blackout at the 4 second range, and that's jumping old Mojos. Take 4+ with a new-ish, vented canopy and the damage goes up exponentially. I'll still do it sometimes, but the body load from those sorts of delays is truly punishing.
Yesterday I took just shy of 4 and cleverly forgot that I had a nearly-new, vented Troll 290 on my back. My neck is quite sore today, along with shoulders and (mysteriously) abdominals. I think I know those delays well enough that I tense my body and prep for the pounding. Staying loose sounds good in theory, but for me I need to fight that shock or I'd end up doubled over in a ball and not very functional for dealing with potential off-headings.
The worst pounding I've ever taken was a 4.3 second delay where I got very head-down. Pack job came out of the container and hit my feet on the way to line stretch - not optimal body position, to say the least. I opened with a 120 right and half a line twist, along with blacked-out, tunnel vsion. I kicked off the cliff, got setup for landing, and somehow got down safely. I hurt for weeks afterwards, and was scared of that object ever since - I still am!
I don't think many folks are into taking 3+ second slider-down delays consistently. There really is damage as a result, not just in the neck but in the lower back. The visuals are fun on some objects, but I'm much more picky about when I'll go deep now than I was in my "young and stupid" days. Now, I'm old and stupid!
I think it is possible to pack so that slider-up deployments aren't horribly punishing, consistently. However, I know of no safe tricks to really soften 3+ slider-down. For those, we just grin and take the pain.
