Too much of a good thing is a bad thing then?

Wasted energy? In bowhunting? Give me a break.

It's much better to have too much than not enough.

Jeff, if you really want to experiment, let me look at work tomorrow. I may have some old weight tubes sitting around that I can send you. If I don't have them your local shop should. They're made by Carbon Express and fit inside any normal 5/16" diameter shaft. Easy way to up your weight without buying new arrows.
