Whenever this subject comes up almost nobody mentions whether they are shooting fingers or release. I've always heard that bareshaft testing applies mainly to finger shooters; is that correct or not?

Should you add internal weight to the rear of the bareshft to make up for no vanes?

Also: When I tune using the walkback method, the fletched arrows line up vertically at all distances, but the bare shafts hit to the left. (Broadheads also fly left of field points no matter how much I move the rest in or out.) It's been this way on eight bows over eight years with four different brands of broadheads with various shaft stiffnesses. String loop and no vane contact. Comments?
