Thinking about ordering some wood arrows for my centaur longbow. I have no idea were to start. I'm shooting a 400 spine Easton traditional axis arrow cut to 30 1/2in. With a 200gr point. Bow is 50lbs at 27. With a draw around 27in. What spine should I order?
Thanks
Jeff
I hesitate to say anything, because what works for me may not work for you. I have a 52 lb at 28" JD Berry. With that bow, I have a 27" draw, give or take. I am shooting 55/60 surewoods with 180 grains up front. The arrows are 29" long, Nock to back of point. 50/55 maybe be better for me. Going to see about that.
In talking with a respected outfitter, he told me the hunters who come to his camp with spine problems are usually overspined.
Snag at Wilderness Custom Arrows or Paul Jalon at Elite Arrows would be a good person to talk to. I don't think Snag is taking new customers at this time tho.
Your arrow smith might be the best person to ask. Maybe he has a test set you could get first.
A few more specs, and we can offer some sound suggestions:
What length do you want to BOP?
What weight points do you want to shoot?
And if you happen to know, how close to centercut is the shelf?
A .400 Axis is about 78# spine. The Centaur being a high performance bow with a low stretch string and cut to center (or is it past?) and the Axis being a skinny shaft, enable more spine. At the same time, leaving the shafts longer and using heavier heads as you have done tends to soften the dynamic spine. So, long story short, if you want to shoot the same length and point weight in wood arrows, you would need about 65-70# spine. Five pounds heavier would probably also work.
A shorter arrow and lighter point would require less spine.
The centaur is cut to center. I was looking to shoot 125gr points, maybe 29in arrow.

At 29", with 125's, I'd say a dynamic spine in the low 60"s. So 60-65's, tweaked if /as necessary, oughta fly true for you. You have room to shorten the arrow, or build out the side plate a bit, if the bow wants a little stiffer arrow.
Just my opinion, and experience with an earlier 'glass Selway/Centaur. As said above, David at Wilderness Arrows doesn't commonly take orders these days. He built a perfect set for my bow, and I'm basing some of my suggestion on what he made up for me.
I would guess 60-65 too, but there's a number of factors to consider. A test set is an excellent approach, because your mileage may vary.
My draw is just a little long of 26". Getting very picking about my secondary aim, cheating by putting a marker on the ground, and shooting 50 pound Acme wood shafts 27" bop with 145 grain heads and 65 pound Acme wood with 190 grain heads 27" bop from seated at 22 yards the arrows fly the same and stack right on each other. With a Centaur your number will be completely different. I personally find that wood arrows are more predictable if they are no longer than needed. i would run the stats of you and your bow on the charts. If your release can at times be soft, like when shooting down out of tree stand, give your self 5 pounds less.
Yep. With the shorter arrow and lighter point, 60-65 should work. Even 55-60# might do it. Follow slobows advice re tuning. If you have the time, might try a test kit.
Thanks for the advice. I'll take a look at a test kit also.

Call Andy at Addictive Archery. He'll ask you all the right questions to get you dialed in. He also offers test arrows that come fletched with points and nocks installed that you can use to fine tune at home and then give him your feedback on flight before ordering a full dozen or more.
Talk to Forresters. they will set you up. the hard maple shafts are hard to beat. bamboo is super forgiving for starters
