Mathews...

You never did mention which aluminum arrow you were shooting. Is it plausible you're better spined, NOW?

If you were over-spined, it wouldn't make much difference in accuracy (at short range, anyways) with a FP. With a BH.....different story.

Congrats on your new setup. My ONLY intention was to point out there's more than one way to skin a cat. Speed is a great thing. It isn't everything, though. Your setup proves it. You're giving up a little in KE (and momentum, also)to achieve it.

At "my" hunting shot distances, I'd go for the heavier. Quieter.....more momentum.....more KE.....etc...

Personal choice.....and I'm sure you'll be pleased with yours.
