RE: Broadhead cutting diameter vs. tissue damage...
Rage 2 blade cuts a total 2''
Slick Trick standard cuts a total 2''
NAP Spitfire 3 blade 1 1/2'' cuts a total of 2.25''
As a comparisona 3 blade 1 3/16'' head has a total cut of 1.78''
IMO 2'' of total cut does a lot of damage no matter how you get there.
