I had an issue just the other day while puttingpracticing for my spring bear season. I am currently using wac ems and have liked how well they fly and how quiet they are the coc design etc. The problem I had the other day really surprised me. While shooting my 3-d target with my broadhead,one of the blades actually broke on impact, I heard it snap as the arrow hit.I was very surprised to say the least,it broke in the narrowestspot onthe replaceable blade.(it was the third shot I had taken with the broadhead). I'm concerned enough to look elsewere. I am going to lookat the new snuffers ss's.
