Help, I've fallen down an arrow spine rabbit hole and I can't get out!
The kid and I have ordered Nika recurve bow packages similar to the one a few posts up thread, and they include a dozen cheap carbon fibre arrows (Pandarus Infinity), available in spine (stiffness) ratings of 400 to 1300. We'll be getting these uncut, but expect to get them cut down to a sensible length once we've got them.
I"ll have 24 lb limbs and estimate my draw length at around 28", so expect to cut the arrows down to about 29-30" long. I looked at a few spine charts and they all seem to say 700 should be OK for me.
The kid will have 18 lb limbs, and I think their draw length is very roughly 25", which would leave their arrows around 26-27" long. I looked a 3 different spine charts and got recommendations ranging from 800 to 1450!
Meanwhile the guy that runs the shop reckons we should both have arrows around 1000 spine.
It's a conundrum.
