Spine question for wood arrow shooters

[cck311]

Looking to try some woodies out of a 50 lb at 26 inch longbow and a 125 grain point. What spine rating would you guess for this setup? From what I can tell from my research 40-45 or 45-50 might be the ticket but I'm not sure. I have a test kit from rose City archery coming that includes 2 each from 40-45, 45-50, 50-55, 55-60. I'm wondering if I should have started at 35-40 as the higher ones are likely too stiff. I'm hoping 40-45 is not too stiff.

If you leave them a little long you will probably be fine. I’d set up a paper tuner and try to get a clean hole at 3’ and 6’ before I was satisfied enough to buy more shafts. Wood arrows are pretty unforgiving of bad shots though.

I know on mine I shoot a 50# longbow at 28” and I cut mine to 29.5” and I have great luck with 50/55 and 55/60 depending on what I glue on up front. I shoot 125 and 160 grain ACE standards, feathers range from 3” to 5”.

50-55 should work well.
My longbow likes 50-55 tapered shafts.
Is it center cut riser? If so go a little heavier spine, 50-55.
