I run 22-11-8 69 rollout 9-paddle haulers w/6inch swinger, bike dynoed at 85 horse and I need more swinger. I am skyward every launch and as I am letting out of it to not land on my lid, slower bikes leave me in the dust. You are only running a +4, I agree w/firehead, 8 paddle b2b hauler(or sls if your guys sand is that clean). W/ a less rollout tire(20x10x10 for example) you will usually have to run more paddles to get the same bite.
