Duncan,
The head looks cool. I like those arrows too. I found a flu flu I had made years ago with 6 feathers on a Easton 2016 shaft. I also found an old arrow from my wheel bow days and removed the insert and cut it into 2 inch lenghts. I then glued a 2 inch piece of the old wheel bow arrow onto the end of my 2016 for footing. I then screwed on one of the "Mace" small game heads Jerry Jeffer showed me how to make and in addition put a flat washer on for some extra weight. Total arrow weight is now 580-590 grains. That should leave a mark when it hits.
