straight paddles do not SUCK for duning. i dune my bike 70% of the time and race/hill shoot 30 % of the time i ride. i have used 10 paddle haulers (straight paddle) for the past 4-5 years and have absolutely no complaints. its not hard at all to whip the rear end of you bike out with straight paddles, just give it gas, and use a little body english to push the back end out. idk, maybe its because ive run them for so long that it seems easy . either way, i think you should run the 8 paddle haulers, with your set up.
