Overpower as much as possible. If your not getting trips then get the twin 400's.
I have quad 400r's on a yf42 and love em over the trip 350 yammies I had on the last one.
More power= better hole shots, no prob getitng on plane when loaded up, less strain on engines, can run at lower rpm's, generally better fuel burn at cruise, higher top end-- everything better imo.
