I am going to try some wood arrows for a change and would like some help with what spine to purchase.  I draw 25.5" on an 60" Arcadian Woods longbow marked 57# @ 28" with a B-50 string.  I also plan on shooting a 125 grn head.  Thanks in advance for any information!

What will be your finished arrow length?  I too have a short draw 26".. ALL of my longbows "liked" shafts close to 10 pounds lighter than the draw weight.. I'm sure cutting down my arrow length because of my short draw is why..

I would start with 50/55 or 45/50 spined shafts. dont' waste time.. cut a few of each spine to what you want your finished arrow lenght to be. Buy the best quality matched shafts you can, fletch them and install points (I tune arrows using broadheads) and using good form see what they do.  If you have perfect flight with a broadhead arrow any field tip will be perfect as well.
There are variables.. Tip weight, fletch size, shaft paradox, brace height, your release...

Let us know what your bow "likes"..

Your draw weight is probably close to 51# at your draw length.

With a standard B50 string and standard 125 grain point if your arrows are about 26" to the back of the point, I'd expect you to be in the 40 to 45 lb range.  If you are hunting with it and would like the extra weight, you could get the 45-50's and leave them longer.  Say 28" BOP to start.  Personally I would shoot some bare shaft and see what they do.  Nock left (for rt handed) is weak.  Nock right is stiff.  Too weak you can fix by shortening the shaft about 1/2" at a time and retesting or adding a spacer behind the side plate about 1/16" to 3 3/32" thick.  Too stiff can only be fixed by increasing point weight or draw length.

It's a bit of a hassle to cut and regrind tapers on woodies but still only use one or two for testing until you find what works.  Don't want to shorten multiple shafts too much and find out too late they are too stiff...

Need to add a disclaimer, I've not handled any Acadian woods bows and don't know anyone who has one.  I've heard good things about the craftsmanship but can't recall any comments on the performance.  Being a recurve, and possibly one with real good speed, you might need one group higher yet in the 50-55 range.  Even then, if you leave them long and play with point weights and length, you should be able to make them work fine.
