After reading Dr. Ashbys report on broadheads, I am switching to a two blade. I like the cutting diameter of the treeshark, but it doesn't look as sturdy as the interceptor. I was looking at Simmons because I have seen some of the pictures on here of deer that have been shot with them. The damage was amazing!! Anyone that shoots those broadheads, I would apreciate the input. I also thought about the Magnus heads, but I only saw them in 140 grain and below for screw-in heads and I would like to go heavier. Also, the Magnus heads look easier to sharpen. I appreciate any input...Charlie
