Arrow spine

[Rons]

I have spine question about wood arrows.i have bow that is 55# at my draw length 27.50 and my arrow length is 28.50 bop . Curious on arrow spine recommendations I was thinking 70-75 or 65-70 , oh the bow is cut 3/16 past center.thank you for any input.

Given it's cut past center, I suspect you're also shooting a low stretch string on a fairly high performance recurve or hybrid.  Given those features, and if you're shooting a standard weight head, say 125-145 grains, either will likely work, but I'd go with the heavier of the two in a 11/32 shaft, the lighter in a 23/64 shaft. If you plan to shoot a heavier head, definitely go with the heavier spine.

I would agree with Orion. Before I saw the 3/16 past center I would have thought you were too stiff but that changes things.

I shot 55# bows for many years and prefered 70-75's. My draw was 28 and arrows cut to 29 1/2 with 125 or 150grn heads
