Don't get me wrong... I throw Roadrunners, Gazelles, Leopards and Banshees for a reason... I am pleased when I am throwing 280 to 310... I just think 300 to 375 is pretty impressive.
But hey, that's me...
I agree it is definately not something to be bashfull about (I have people who only throw 325 beat me on a regular basis )
I second that a dx eagle makes a great driver for just about any power level, I remember throwing MASSIVE hyzerflips w/ a 150 class dx eagle, really they just looked huge, getting about 80' left right at over 50' of height, but only traveling 400' forward . they are great for control, and are easier to flip up than a teebird.
get muddy, knowing you used the pro starfire as a turnover driver, I am geussing it was alittle worn, I would reccomend the avenger over the starfire, thinking the avenger is more stable than the starfire and may be one of your best choices for max d.
