Thanks for the feedback. I was looking through some stills from my GoPro this weekend and I saw something very interesting. My slider, although collapsed and secured on the back of my jumpsuit was riding several inches up the risers and actually had the rears engaged (bowed back a couple of inches). Basically I was flying in rears constantly.
I guess between that massively wide slider, the higher attachment point (on my jumpsuit collar), and additional drag from the larger slider, I need to do something to better secure the slider to the base of the risers (or just go with a removable slider).
