We've played in primarily ASA tourneys this year and all but one have had 3-4 pool games with all teams advancing to single elimination on Sunday. When I was coaching boys baseball and slowpitch softball, most tournaments had pool winners and some wildcards advancing to double elimination. Sometimes you got a good draw in pools and sometimes you didn't, but I liked the fact that we had to play well in pool play to make it to Sunday, but you could have one off game on Sunday and still have a chance to redeem yourself. We've had several tourneys this year when we've swept through pool play and then got knocked out early Sunday either due to one mistake or due to facing a lower seeded team that didn't care what they did on Saturday. It would seem to me that having pool play count and going to double elimination might also be better for TD's when they have weather issues on Sunday. First of all, there would be less teams around trying to get their one game in and secondly, the TD could hold the option to go to single elimination if necessary. I know that most baseball tourneys are still run that way today.
