So,

is it safe to say that

overspined arrows result in left misses from intended target and underspined arrows result in right misses?

Not quite that simple.

I think you are thinking about recurve shooters
who shoot fingers and are right handed.

I also shoot recurve.

Due to something called archer's paradox,
the string has to move around the fingertips
upon release.

A stiffer than required arrow,
will miss left for a right handed recurve archer.

A weaker than required arrow,
will miss right for a right handed recurve archer.



For a compound shooter,
using a release, there is no "archer's paradox".


All arrows bend right after release.
Finger shooters. Release shooters.

For a release shooter, the arrow bends
differently than for a finger's shooter.

For a release shooter,
a noticeably weak arrow shaft
will behave inconsistently
resulting in larger groups.

For a release shooter,
a noticeably stiff arrow shaft
will result in great grouping
and bullet holes through paper
for the bow technician at the shop
as long as he has PERFECT form.

For us mere mortals,
it is much better to have a properly
spined arrow shaft (correct RANGE of stiffness)
(yes...there is a range of stiffness that will work)
so that the arrow will still behave predictably
and "forgive" small form errors and inconsistencies on our part.

That is a general rule of thumb but it will differ with the bow and the shooter (left handed/right handed)

Well in any case it's way better (and safer) to shoot a stiffer than weaker arrow...

Has not been that way for me... Overspined goes where aimed... 20 yards... 60 yards I doe no... I shoot 30x pros..

in my humble opinion,,,, and I am not that good a shooter... yadda, yadda...

thank you, very good info.

I know there is a lot more involved but this is all very useful.

rarely can you be over spined. very few bows will not shoot a stiff arrow. i've shot all the big names and the only one i've heard react to too much spine is a bowtech patriot. thats due to the single cam and unlevel nock travel the one i shot would not paper tune a carbon express 400. you had to go to 300's
