I'm looking at making the switch back to wooden arrows and am leaning towards hickory since I don't mind straightening but I get real sick of the POC's breaking.  I shoot a great northern, fireball, 60 @ 28 and I draw exactly 28. I want to put 175 grain tips on them. I would love some suggestions on spine and a reputable manufacturer.

Contact alleghany mountain arrow woods he has about every shaft you can get and is very knowledgeable.

I have a 59# @ 27" Stewart slammer  62"  and my arrows/shafts came from Allengheny arrow woods tapered hickory 60- 65 so with the heavier head I would shoot 65-70 tapered-  Bill's shafts are great and I highly recommend him.

Raptor Archery gets my vote...very good quality shafts matched by excellent service...

I tried some hickory quite a few years ago. They were too heavy for me. They dropped alot after about twenty yards.  They were very strong though. Gary

Ash is another option. Tough but not as heavy as hickory. My ash arrows are generally at least 100 grs heavier than POC.
Hardwood shoot arrows or cane also make very tough and relatively heavy arrows.

PM sent...

I have some 60-65 and 65-70 hickory tapered shafts from allegany that haven't been touched i would be willing to sell. Send me a pm if your inerested.

Talk to Orion, he ordered us some from Allegany Mountain Woods, I'm keeping mine, he is selling his (stained, crested & sealed).  Great shafts, good quality, strong, heavy, may not be or remain as straight as POC, however, more than adequate, depending on your on your intented use.  Consider short range, max. penetration.  We ordered ours 5/16" parallel, untapered at 32" they weigh about 695-700 grains.  You won't be disappointed if you like wood shafts and like to experiment.

I also would recommend Allegheny Mt. Arrow woods. Great to deal w/ plus top notch shafts. I shoot his ash,& laminated birch. Heavy, tough, & easy to straighten.

I thought about ash as well, but would prefer to stay out of the 23/64 size shafts. Thanks for the info.  Were those shafts running 700 grains with the head or just the shaft alone?
