RE: How do you guys like..
I've always preferred 4 blades. They cut more. No 2 ways about it. I have had good results with several 4 bladed heads. Even one of my favorite mechanicals back in the day was a 4 blade. I doubt you will find much difference in the cutting of the longer versus shorter broadheads. The longer design might have an edge in penetration, and the shorter should have a slight edge in flight out of less than perfect setups.
