Re: [CanuckInUSA] Injured jumper near Phoenix
I am not recommending Daves choice of gear, but I do understand what Kevin is talking about with the micro lines and slider configuration:
Im guessing most BASE jumpers have never BASE jumped (or seen BASE jumped) micro-lines on a large 7-cell. I made about 25 jumps on a Dagger 266 with micro-lines a few years ago. There is a big difference in the way a canopy opens with micro-lines. Basically it will slam the ever-living-hell out of you if you go 2 or more seconds without a slider. With a slider it still opens very fast, even if youre doing just a 2 second delay. Three second delays with the Dagger 266, with micro-lines, with a mesh slider produced basically an instant opening again and again with total consistency and good heading performance. While jumping that Dagger, I never worried about it sniveling.
I came to the conclusion that the drastic difference is because Dacron lines stretch some during opening shock whereas the micro-lines dont stretch much at all. Also, the slider moves down the micro-lines with very little to no resistance. I also wondered if the little bit of difference in the wind resistance (drag) of Dacron VS micro-line could be a factor.
I would never want to have micro lines on my own personal canopy because of how hard it opens with no slider. But, for someone that does use micro-lines, I totally understand why they would want a slider with a 3 second delay. I guess one reason someone might choose that gear configuration is if they didnt like slider down openings in the 2-4 second range but still wanted something that would consistently open quickly.
Think about this:
Youre jumping a wall big enough where you will be doing a 5 or 6 second delay.
Which set up is better?
Personally I would choose my canopy with Dacron lines, mainly because thats what Im use too. An experienced micro-line pilot may have an edge at this delay range............I dont know.
