I bought every single size to tune my arrows, but now you don have too. I found the 200 and 250 work great for spined arrows for a 65 and 70 # bow, out of my 55# bow. But a prayer answeres maybe 3rivers is on top of things.

I hadn't seen those before...just the test kits for the arrows themselves. They are on top of things, I am impressed!
