I think their past offerings were less than stellar, but I have been shooting the new Buckmasters by ABC. They have new blades, that stay sharper longer. I have used the regular Sonics in the past, and used them successfully without damage. The arrow I sent through a doe last season had small nicks in the blades, after the pass through it came out in one piece, and stuck in ground another 6". You really have to tighten the broadhead down to keep the blades together!
I shot the Buckmasters into my Block 4x4 10 times, and they still shaved hair. And they were in one piece!
I got a few to test out on a doe next weekend when I go down to Peoria!
