Spine question I've seen before here

[D Durham]

But I can't remember. I got loaned some arrow to try and I'm right handed and they are 4 inches right at 20. Weak or stiff? Thanks in advance.

[McDave]

Assuming you are capable of shooting a tuned arrow dead center, it is likely that the arrows are weak.  Absent that assumption, it is more likely that one or more form errors are causing the arrows to impact right.

[D Durham]

Yes, form good, shoot good. No issues with hitting consistently where I'm looking. with several set ups. These arrows just aren't agreeing. Thanks again.

[Mint]

If they are kicking left a little and hitting right then they are too weak as was posted above.

I'm glad I found this thread as I too have the same issue with some arrows I picked up for cheap at a yard sale. However, I'm not really seeing a kick.
