Jim,
Point taken.........it' s been a little like pulling teeth to get enough info to even form any opinion.

I guess the jist of my advice is that (I think I can tell already that Nuge is gonna try a mech regardless of what anyone says.....I just have that feeling) And if I' m right (Am I right Nuge?) , if I' m right, I want him to at least be using the ones that will give him the best chance for success given what I do know.
So given your good point Jim........yes Nuge if you are in doubt, and it does seem like there is a little doubt still there? A good fixed blade head is always the safe bet. If you ARE going to try a mech do yourself a favor and don' t stray from the styles I mentioned.
The rest of my advice Nuge: Weigh your finished arrows on a scale........shoot thru a chronograph and then you' ll know. And knowing is half the battle.
