I currently shoot POC tapered arrows. They shoot grea but I am about due to build up another dozen. I see a lot of you are shooting Surewoods which is Douglas Fir. I also see Hildebrand sells tapered Douglas Fir and Sitka Spruce. They also get a lot a praise here. How does spine compare between these different woods. It seems to me 55-60# spined arrows wood shoot the same no matter the wood as they have been tested for spine. Are you guys typically able to switch between different of wood using the same spine weights?
Yes!
With woods that had a similar mass weight/density, I could, but not with others.
For instance, I could shoot basically the same spine (or very close) in spruce, POC, chundoo, Norway pine, Canadian Pine, Hex-pine, SuperCedars, and Douglas fir.
When switching to a wood that was much heavier in mass weight--maple, ash, etc.--I have to go up around 10# in spine.
My guess is the extra mass weight acts similarly as a heavier point. I shoot full length arrows, so there were some major differnces in shaft weight when switching from soft woods to hard woods.

Thanks. Since posting I figured out a way to better answer my question. If I had 3 arrows all tapered 55-60# spine range, one arrow POC, one Douglas Fir, and one Sitka Spruce would they fly basically the same out of the same bow.
If they're the same physical weight, yes they would. Chad nailed it above. My experience as well.
"If I had 3 arrows all tapered 55-60# spine range, one arrow POC, one Douglas Fir, and one Sitka Spruce would they fly basically the same out of the same bow."
Probably, unless you got some shafts on the extreme ends of the weight range.
Spruce is generally the lightest of the ones you listed, Fir the heaviest. So, if you got some of the lightest spruce and the heaviest fir, you might not get good results.
If you find the light ones are a bit stiff, increase the length and/or point weight--or just the opposite if the heavier ones are a bit weak.

Thanks everyone. Sounds like I can safely build my next dozen with any of the three w/o much issues other than possibly playing with point weights which is cheap and easy.
I have
I shoot POC and chundoo and have used Sitka spruce in the past, all with no difference in performance for the same spine. In fact, right now I am shooting cedars and chundoos interchangeably , and they all go to the same spot when I do my part.
Yes, go for it!
