Longer shafts would fix it, but I'm imagining that you want to keep your current arrows this close to the deer season. I like them longer myself.

Is there enough room to rotate all of you rpoint inserts so that the blades are oriented in such a way as to give you maximum clearance? Would that give you enough room if they were rotated just right? I'm guessing you may have thought of this already, but if you have a 3 blade head, it just might work.
