I have 6 XX78 2514 shafts cut to 31" . 5 of them have Thunderhead 100 broadheads on them. The last shaft has a 125 grain Satellite 4 blade head that I cut two of the blades so they are prongs. Cutting the blades reduced the overall weight to just barely above 100 grains. I reserve that one for any turkey that is unlucky enough to pass the stand.
