Agree on .25/.50, but .50/1.00 might be even better. Just because you have the roll doesn't mean you should play higher if you're not a winning player at your level. Fix your leaks at a low level, but it has to be high enough that it might start to hurt the players in the wallet if they play like idiots. FWIW, if you don't care about paying a little "tuition", play at the highest level you can stand to win money at. It will make you a better player in the long run.
