if not for bumping this.
when you're playing on a small bankroll, i'm talking about one that can't be replenished easily, i think you're better off decreasing variance. when you have a winning playing style, you can get your bankroll up to where you can endure the swings and then maximize the win rate.
clearly if you work on maximizing your win rate and going broke in the process you win nothing.
therefore, get your bankroll up there first, 300 is suggested by most books, if you have a nice sample size and know about confidence/deviation/variation you can calculate the needed bankroll yourself. (after playing with the maximize winning strategy for the sample size, obviously)
