Best guess on arrow spine for my wife

[Lone Ranger]

She shoots a 58" RD longbow by CostalBendBows. 46@ 28" and she pulls 26". It is cut to center or maybe 1/8" past.

We also have a good friend staying with us right now that made the local university archery team-

She is shooting a 64" recurve (a Browning Medallion) 40#@28" and she draws 27" her bow is just cut to center or possibly 1/8' before center (tough to tell on it)

What spine arrows should I be looking for? I was thinking 35/40 but maybe that is too stiff? I am going to do wood shafts, so they can make their own.

I would like to use the same spined arrows for both bows if that is possible.


what say you?

I would look at 40-45 being both bows are cut to center.

I think the only way to get arrows of the same spine to work is to vary the point weight. The heavier bow will need a lighter head than the other...IMO
