Yup, another thread from the UG. This one popped up a few days ago but quickly got interesting:
Lot's of interesting opinions being thrown around by experienced grapplers about the way they approach progression in skill. Also, Todd Duffee drops in on page 6-7 and offers his opinion.
Seems like it's split up between 'chess players', the guys that think ahead while rolling and drill a lot, and opportunistic rollers, those that barely think and 'go by feel'. I'd put myself in the second category, though I do like to break down positions before hand when I attempt new things.
