I am currently looking for arrows made in usa. I need arrows that take an s nock because of all of the lighted nocks I have. I have two bows and would like to be able to use the same arrows in both. Both bows are identical except for the poundage. One is a 60-70 and the other is 50-60. I shoot one at 67lbs. and the other at 60lbs. My draw length is 27.5 inches. I can cut the arrows to any length. I shoot a thumb release. I like the Beman ICS Precision Hunters but am open to other suggestions. The charts recommend a 400 spine. Should I go with the 400 or would the 340's work?

Just say "NO" to 400's. I'd stick with the Bemans in a 340 or even 300.

You can cut the 400's to 26.5"s and shoot up to a 175 grain head and be just fine. I know X-man knows his stuff but even he can be wrong, I promise! Shawn

I honestly do not think you will find one arrow to work with both of those, a very well tuned arrow anyway.

I shoot 60#. A long 340 works, or a short 400. That’s what I find anyway .

I shoot 66-67# Mathews ZXT and draw 27.5"s and shoot a 26.5" .400 and 175 grain point weight and it is plenty stiff. I also have changed limbs and shot 59#s last year due to shoulder issues and I did not have to change a thing but my sights a bit. Shawn

Had similar challenge with 2 sons one with 60-70lb bow not fully cranked and other wtih 50-60lb bow. At that length, 400 worked best for us on both bows. I had tuning inconsistencies with stiff 340 arrows (the 30" ones I use but cut down for them when I bought newer ones) and much tighter groups with the more forgiving 400's. Despite most folks here saying spine is not as significant with dropaways and release, I seem to really notice the difference (of course I have 5 different family members bows to tune at different draw lengths/weights with less mature form shooters so I get lots of varied and sometimes interesting if not unexpected results). I will admit that my latest bow purchase for my youngest son had no tuning differences regardless of spine (sighting but not tuning) but his brothers bow from two years before is one of the most finicky.

I would say stick to 340s
