6 max my default stealing range on the button is around 45% of my hands.

Against a full ring nit EP opener, you can't play nearly that many hands because you don't have pre-flop fold equity.

edit: Actually 45% might be too tight for PS 200NL....
edit2: Online full ring at 50-200NL+ I'd raise ATC unless one of the Blinds is known to be loose.
