Rick,
I have shot Snuffers in the past and liked the result on deer...having said that look at the Ashby reports and you will see that single blade, cut on contact, single bevel broadheads have come out with the best results on bad bone hits......I have decided that is what I am going to shoot. It has been said here before its best to prepare for the bad hits and then you are still set up when things go right. I will be shooting Single bevel Tusker Concordes with a tanto tip that I am getting from "Git er Done Archery" (Canadian shop so no duty, and a sponser here) My heads will be 250 grain with the steel adaptor and I will load the front with a 100 grain brass insert for 350 grain up front (again Dr. Ashby's studies)
Good luck with your choice
You might want to look at the Abowyer heads on the sponser page as well they look very good.
Allan
