Powerguy, I currently run 23" Mirages but can literally run it straight to the rev limiter in an instant (around 500hp each). I am going to be trying a pair of Bravos also but like you only because a buddy of mine has a pair on his Donzi that he's willing to let me bolt on. I think Outlaw has it nailed on the head with the Q-IV's. I would even settle fo a 1-2 mph DECREASE at WOT if I could gain 7 in the middle. To make a gain at both ends is just lagniappe (pronounced: lan-yap). That's Cajun French for "a little something extra".
