I have gone thru the majority of them, and came to the conclution that NAP thunderheads are the simplest and easiest to get to group with field points and just work.

I see my friends do what I used to do and buy ever whiz bang head out there. Thinks that cut on contact, and spinny things, and all kinds of craziness and they struggle with broadhead tuning and struggle groups. But I bet they will come back to the good old thunderheads.
