wat size arrow should i use on a 60lbs draw weight.

Arrow spine depends on alot of different factors, like arrow length, point weight, cam type and many more. Your question is very generic and would be answered better if you gave more information. But for most 60# setups a .400 spine arrow will work.

I use 400 spine at 58 pounds for target arrows, cut to 28 inches. But for hunting I have to go to a 340 spine, because I use a 220 grain broadhead. You'll be fine with 400's. Unless your shooting a heavy FOC or your real short or real long on your draw length.

i use 28 inch arrows.with muzzy 125 grain.

A .400 spine will work great for that.

ok thanks for the help
