Well, after scrapping all my misc BMX frames, wheels, and parts, I have about 750 bucks, and I have decided to get into downhill style stuff, like the stuff most of you run. I have done some research and decided I want a full suspension bike with disk brakes. I'm not sure on the size, as I haven't ridden a bike in a few months, and have never ridden a MTB. I'm about 5'7" and 125 LBS, so I would probably need a smaller bike. Can any one point me in the right direction? Any help would be awsome.
