You should use what you feel confident with.
I use a broadhead that I know I can put where I want it to go. That is confidence.
When your out there hunting you should believe that. If you don't feel that way about you equipment, than your chances for success is greatly reduced.

If you can tune your bow to get a decient hole in the paper, there is a good chance that any of the newer smaller ( the one inch size) 3 blade heads will fly true, without a lot more tinkering to do. The mechanicals should fly true also provided you have that good hole thru the paper.

Good luck.
