I really hadn't thought too much about the vest before I hurt my back. It seems like it would be cumbersome and would take a lot to get used to. It looks and sounds like it's a lot of hardware to pack around but if it works like everyone says, I might need to try one. I never really thought about the competitive edge that it might provide but if it lessens the load to your body that much I can see where a person would feel as if they could be at a dis advantage. Since I have yet to try one, it would be hard for me choose sides. As for Jeff Milfords case, I think that it's awesome that he can ski at his level after having a serious back injury. At this time, I 'll thank God when I'm able to ski again with or without a PV.  Â
