RE: whats the difference
Do yourself a favor and try the Blazers. They are very durable and fly my arrows extremely accurate.
I actually went through my archery tackle box over the weekend trying all sorts of old broadheads with the Blazer vanes. I honestly didn't have a broadhead that wouldn't group with my fieldpoints.
I even tried one of those old Bear Razorheads. I've had that broadhead since I was 17 years old (for 22 years!) Even that razorhead grouped with the fieldpoints! I was stunned!
