anyone??? is it worth the $100+ for it? seems a lil too risky to throw money out there and in turn, it be a rip off or something. I mean I'm pretty healthy with my weight and all, but I just wanna try it out and see what all the fuss is about especially getting closer to grappling tournaments and such, wanna see what it does for me health wise and what the whole dieting part is like. I've heard you get fantastic results if you stick with it. so any of you Sherbro's tried it out and if so, how's the success been for you..?
