Instead of what the 20 does not do I think the focus should be on what a 20 does do. It give big a** people like me a platform where I can "potentially" be competitive. at 215 pounds (down from 235) I can not be comptetitve on an F18, ask Jake we tried. You want to pump up the 20's build one out of carbon.
Without a 20 class right now, I'm on the photo boat.
