I used them last season and will definitely use them again. My advice is to be smarter than me and practice using them with someone who really could do without them. My first time using the pants was with a 100 Kg quad. The learning curve was steep.
I really wish I had the option to get Skydiving Magazine instead of Parapoopist with my USPA membership. Or not get any magazine and pay half of what a membership costs and just read the magazines in the DZ bathroom.
