Ok I weigh 127-130, so really small guy and the lightest guy in my whole class is 160 and he isn't good at all technique-wise. The next lightest would be my instructor and he's around 180 and the others are prolly 200 and up (from the muscle ones to the fat ones, but nobody's even NEAR my weight). So every time I roll with the people there I can't help but to think its really playing a lot into stuff like when I don't get sweeps cuz I don't have the power. But I've been reading and a lot of guys say technique over strength, and I can see that but is that too big of a difference? Whadya guys think?
