Almost always I use my customized buttons postflop , I use 33% , 48% , 66% , Pot , sometimes I change those numbers based on the circumstance!
Pre flop I keep things simple as for the pre flop open raise sizes , I open 2.5x-3x when the stacks are super deep 100+bbs and after that I don't bother much with the 2.1x or 2.2x I min raise the unopened flop.
In cash games I open raise everything 2.5x and post flop I have almost the same bets and sometimes some overbets.
