well kron is the main instructor and we do standup sparring at least twice a week if not more so i would say it is a 70/30 ratio, kron has really good standup so he likes to incorporate that into his training, he has sick seionages (sp?), literally threw me onto my head one time
i did get to train with rickson last week (not roll with, i wish), he came in during open mat and showed the more dedicated people that stay late some guard passes, it was amazing to watch kron do the guard pass pretty good on a brown belt and then watch rickson do it to perfection, the brown they were doing it on is dope and rickson effortlessly tooled him and it was funny when kron was doing it, he's just shakin his head talkin shit, lol, even though kron did it well just not perfect
