ccropley,

I haven't used the 100s' but I've been using the thunderhead 125s' since 1986. I have taken numerous whitetail deer and wild hogs with them. I have never had one fail me. I resharpen them after every shot and have used them over and over. I have tried the same type broadhead from sattelite and have not had any problems with them either, just partial to NAP products. I use both a 55 lb recurve and a compound set at 65 lbs and they shoot well out both bows.
