You should consider FOC (Front of Center) balance of your arrow. You can certainly go too light and change your spine of the shaft just as sure as you can go too heavy. If your considering dropping broadhead weight just to pick up a few feet per second of speed, well, your crazy...simply put the difference cannot be picked up in accuracy....keeping correct spine is more important. If your thinking of swaying from Thunderheads, your better off with 100 grain Muzzy or at a minimal, 90 grain Muzzys.
