i'm adapting more to the true bfly as when done right it's amazing, esp on the lateral movement. however, i still show some stand-up style from my youth on occasion (as you can see from my above picture). it's not a thought out "save selection" process just old school instincts kicking in mostly during scrambles.
in retrospect some of the occasional two pad stacks/poke check combos have thrown off some skilled shooters who are used to pure bfly goalies. but it's all instinctive to the situation, how much control and speed the shooter has, angle you have etc...it's nice to be different though.
