I am setting up my new bow and want to get everything as close to being right to start with. The arrows I have at the moment are Easton Flatline 400 spines cut to 27.5". I have not shot them yet but I am sure they will be overspined. I think I need a 500 spine or close to it. I would like to keep the arrows in between 26.5"-27.5" long with a 100 grain tip.

Can somebody run my numbers to see where I might need to be.

2010 New Breed Genetix split limb
58# draw weight
27.5" draw length
Limbdriver rest

Thanks in advance

optimal spine 0.3634


according to OT2



500's will be insanely weak

You just spent all this money on a new setup.....what's another $20. Just buy one of the programs.
