I guess that it's because I can't afford it. I have three freestyle
boards
now. -snip-

I don't know much in the way of what works well for 100 pounders, at least
not with soft boots. What freestyle (please note sizes) are you riding, and
which one works best for you in races? We might have some suggestions but
need to know what size you're comfortable on now. Also what size are your
feet?

You might ask over at www.bomberonline.com as well. There are several
folks over there who coach, and some of them might have some ideas.
