Help building arrows

[5MilesBack]

I realize I am totally cutting against the grain on a message board with this many experienced folks, but my recommendation to you is 340 spine, shaft cut to your preferred length and 225 grains up front. If it doesn't work, that's ok, you jump to 300 spine. You'll find carbon arrows are very, very, forgiving on the "softer" side.

I've been known to tune up some underspined setups, but his 80lb/30" draw setup would be equivalent to a 70lb 32" setup.......and those 340's will be way underspined even without the 225 up front.....unless he's somehow shooting a 25" arrow.
