When using the charts for arrow spine selection do most use poundage as listed on the limbs or “Off the Finger” poundage at full draw? Or does it make any difference? In my case a 2 lb increase. Over thinking it? Make any difference?

Also just noted some new GasPro spin vanes “ Parabolic Soft + Ultra.” Anyone try these? Got an evaluation?

It would be the poundage on the fingers. The charts are sometimes wildly off when you actually try to tune though, depending on the arrow, so don't trust them too much.

I don't have experience with the GasPro vanes unfortunately.
