As someone who is relatively new to APAT, I just want to say the starting stacks and structure are spot on. If there is to be an increase in starting stacks, then as others have mentioned, to get to finished at a decent time on the Sunday, you"d have to lose levels. For me, I"d keep it as it is. The current structure creates pressure for the players at the right times, without ever turning into a crapshoot.
I"ve never had the opportunity to play Omaha, Razz and Stud live, and would love the opportunity ( especially as it"s not expensive).
