I'm torn gutfirst. I think the rules from the 80's, at least as shown from quick_single's posted matches, are far superior to any recent rule changes. I think the new rules, on average, create more exciting bouts than the ones in the early 2000's which often ended 3-0 or, worse, 1-1 referee's decision after 9 minutes. However, the new rules do showcase some really, truly awful matches (ie 84 kg world finals this year) that wouldn't have been possible before.
I do like the push-out, and I don't the clinch the way it was when I was wrestling, at least in Canada... defensive guy got a chance to get set and a real takedown had to be scored before offensive guy got a point. In some international matches they let the offensive guy start almost in a double leg, or give out really chintzy points (watch the Dudaev/Batirov match on the good matches thread); that drives me crazy.
I didn't like the reverse lift greco rules at all- waaay to many 1-1 last-point-wins rounds. I'm not sure how I feel about the newest incarnation yet- maybe if FILA would put the damn worlds matches on Webtv already I could watch enough to get an idea. The world finals were decent, and the 74 and 120 kg matches were excellent.
