That's why my broadhead of choice this year has 3 blades at a 2" cutting diameter.

Wish I still had the 4 blade 2" ones.

But see now your cutting surface thinking becomes ifs and buts depending upon blade orientation as it passes through the tissue.........I have shot lots of animals with a flotilla of different heads and I don't have any scientific proof of it other than my own eyes but as a whole I've had deer run less distance after the shot with the big stuff than the more modest 3 and 4 blade fixed heads.

Of course my thinking and style isn't for everyone either as I also have the snot in my bow set ups to shove these big things around and through animals consistently.

Sorry for screwing up your post Bigbulls.......geez you'd think after 8 years here I would know how to work all the buttons.
I wanted to hit QUOTE and hit EDIT by accident sorry man! [&o]
