As to chute rigged A, send an email through the usaca website about that issue www.usaca.info . Ask for Dave Carlson to respond about that and he will talk you through his changes for using a chute. Additionally, there are some platforms that are better than others for heavier sailors. Others in the class can steer you in the right direction. Personally, I am staying with A's instead of switching to F-16's. I like the development and size more in the A Class.
