HJ:
The Shkote broadheads were advertised, at least at first as THE dangerous or BIG game broadhead. From what I understand some people tried and were less than impressed. Old standards seemed to be the ones preferred.
Having said that, the major problem that most people had with them, was that they appeared in pics to be a two bladed version of the three bladed Montec. You used to be able to get the Montec in up to 145 grains. One problem some have had was the angle of the blades is pretty steep, much greater than the "ideal" of 3:1. I haven't had a problem, but then again i'm not hunting anything bigger than whitetail and the 145 Montecs fly pretty well.
Where to find either the Shkote, the B-52 and/or the heavier 145 gr. Montec - best place I've seen is E-Bay, where I've seen all three sold recently, for very modest prices. Try there.
