OVER-Spined?
I've seena few posts about people being OVER-spined.
I KNOW my hunting arrows were over-spined. What's wrong with this?.....assuming you've got plenty of push (fps/KE)behind the arrow?

RE: OVER-Spined?
Slightly overspined is ok, and with a dropaway even more overspined is probably ok. The spine lets the arrow bend slightly to help clear the rest. To much bend (underspined) and it doesn't recover, not enough bend (over spined) and it sort of "bounces" along the rest.
You can always "weaken" an overspined arrow by shooting a heavier BH as well. this also ups FOC which also helps accuracy. Can't really make the same move to stiffen an arrow.

RE: OVER-Spined?
There is nothing wrong with shooting an "overspined" arrow as long as it's not doing anything funky. Out of everyindoor or 3Dbow setup I've ever shot, I've never seen one that didn't fly well with a severely "overspined" arrow setup. The only time I worry about correct spine is for a field/fita archery setup where I will be shooting out to 90 meters, and a fixed blade broadhead hunting shaft.
Every of my best indoor games, and even my best 3D games were shot with "overspined" arrows. I cut them 1/2" in front of the blade on my rest, and never seem to have a problem.

My GT 7595's are borderline "overspined" for my 29" draw at 70#. When I drop to 60#, I know they'll be overspined. I'm not certain how a 500 grain total weight, .300 deflection arrow will do out of a 60# setup. It sure would be slower than I'm shooting now. I'll bet the bow would be quiet, though.
Good question, Jeff. It'll be interesting to see what everyone thinks.
