Overspined VS. Underspineed

813 Views 10 Replies 6 Participants Last post by  ELKhuntR
Hey Fellas,
Below are tips to improve broadhead flight.
Please try to explain this to me. I'm having a heck of a time understanding this.

if an arrow is underspined that means it's too weak, correct. Why would you increase bow weight or decrease arrow spine when it's already underspined. Am I mixing this up?

And if an arrow is overspined, wouldn't that mean it's too stiff, which would require a heavier draw weight or decrease in spine or broadhead weight.

3. Arrow underspined, increase bow weight or decrease arrow spine or increase broadhead weight.

4. Arrow overspined, decrease bow weight or increase arrow spine or decrease broadhead weight.

any help would greatly be appreciated.

You have it backwards, my friend! :wink:

If an arrow is overspined, that means it is too stiff for the draw-weight and point-weight you are currently shooting. To make it shoot well, you need to:

1) Increase draw-weight....
2) Increase point weight....

If an arrow is underspined, you need to:

1) Decrease draw-weight....
2) Decrease point-weight....

Make sense now? :)
how does that relate to right and left misses from where your fieldpoints hit.

If it's hitting left is it overspined.

and if it's hitting right does that mean it could be underspined.
anyone have an idea on this

overspined relates to left misses and

underspined results in right misses

Is that right?
I know there are other ways to tune but seriously I need to figure this out.

one queston,

does overspined arrows relate to left misses and underspined to right

and is overspined arrow is too stiff while an underspine arrow is less stiff.
thanks Bronz and everyone else

I think I got it now,

Elk: The best thing you could do is pick up a copy of the Easton Tuning Guide (or download it). Bob Ragsdale's site is also full of good info.

Re. the lefts and rights, that may be more relevant to a finger release than mechanical release. In my experience, if you're using a mechanical release, it's hard to have an arrow too stiff.
thats what I've been hearing. I think my original source is a little outdated.
