What spine for shooting wood arrows from a 51#@26 Thunderstick MOAB?
Thanks for the help,

65/70 for a standard point, add some for heavy points.
Shaun is liable to be pretty close. I'm pretty sure the MOAB is cut to center. For a 28" arrow and 125 point, I'd start with 60-64 and look up from there. Bring it to K'zoo this weekend and I'll have test arrows you can try out.
My Moab is not cut to center. If your only pulling 26" I think I would try 50-55 or 55-60. The best way is to try the test arrows and shoot different ones.
I have a 52@27 MOAB, and shoot 45-49 hexpines (11/32) out of it, cut at 28". That being said, I also shoot 5/16" 50-55 Laminated birch cut at 27 BOP out of it, both with 125 heads. My latest batch of arrows are 5/16 hexpines, 28" long with 200 gr on the tip, spined at 50-55. All of these combos fly like darts, weight from 565 gr for the first set, and the other two sets weight around 620 gr. All shoot fine, MOABs are very forgiving as far as arrow spine.
I'm not 100% sure, but seems to me Jim cuts his risers 1/16" short of center shot. These reults may vary slightly depending on your draw length, and the length of your bow.
For me, I've tried stiffer shafts, and they flew stiff. Good luck.
My bow is not cut to center and likes a little weaker arrow than my center cut bow of the same weight.
I have one that is 52# @ 30" and use 60-65# out of it. Hap
what's already suggested will put you in the ballpark, but it's gonna take some experimentation on your part to hit a home run. ain't no short cuts to matching arrows to bows to archers. good luck! :wavey:
If you try the Arrow Dynamic Trad Lites you will most likeky have the arrow that will work. They work in bows from a really wide range of weights. Then you will just have to play with length and tip weight to find out whats best for your setup.
