Tiller gets a little weird (to me) with cam 1/2 and single cam bows. I've always bottomed out the limbs and then backed them off equally to the poundage I want. If I set the nock point even with the rest and have a high or low tear through paper I'll tweak the tiller a bit to correct it but I've only had to do that on one bow. I'm betting that dime that you won't see any measureable difference by setting them equal. I think it was Arthur P who discribed a method of setting tiller for a balanced feeling draw so that as you draw the bow one limb doesn't came back in toward you before another.
