So I have the opportunity to pick up some POC shafts but was curious about the spine. I shoot a Black Widow PMA 45# at 28" which I draw to 27". These shafts spine at 40-41# full length. If I cut them to 27 3/4" BOP and used 125 gr. heads, could I get decent / safe arrow flight or would they be underspined no matter what I do? Never shot POC but would love to make some up. Thanks
Those might be a touch weak...
Yep. Too light.
That's what I was afraid of. I will just have to order a set of 45-50 sure woods or POC. Thanks for the replies
For a PMA, I suggest adding 15 lbs to your draw weight for a 125 point and 28" BOP. 55-59 lb spine.
Why 15 lbs if you don't mind me asking? The three rivers calculator shows an almost perfect match at 47# with that set up. I am shooting 50-55 ramin shafts that I had made for another bow with 145 up front and they are way too stiff. They are also really heavy though...
Just call Steve at Surewood...he knows as much about required spine as anyone

I also think that the 55/60# spine if you stay with 125 grain would work out a lot better. Steve
