I think you have to ask yourself if you are just looking for an arrow that flys well or are you looking for the arrow that shoots the broadhead you want to hunt with well. If it is the former, you are there, but if you don't necessarily want to hunt with a broadhead of the same weight as the tip on the arrow that flys well, you might have to experiment with differnt shafts.
And like Jake said, you will want to make sure the arrow not only flys well with a field tip, but also with a broadhead.
Wish I could get them to fly that well. I think I'll be experimenting forever.
