I like hex heads more and more.
I like and have others, like the VPA and the similar head sold by 3Rivers, they are devastating on a hit, but I have found that these wider heads broke a LOT more arrows on glancing hits to trees and stuff.
I have even made my own fake hex heads by taking a standard glue on blunt and drilling out a dished area (I made a simple jig with 3/4" plywood, drilled to fit the head, and using a larger drill bit, like 1/2" to 3/4"). They work OK, though not as well as a real hex head. But they are substantially cheaper.
