Ok, I've been shooting my Envy at 62# 30" dl 30" cx maxima 350 hunters 422gr 295 fps. I have two pins on my sword sight for 20 yd & 40 yd. I feel comfortable shooting from 0 to 50+ yards with this setup and I'm very pleased. I need a few new arrows and will probably keep what I'm shooting now unless there is something to gain...I could cut at least 2" off of my current arrow and still be ok, or I could shoot a 28" 250 going by the CX chart. I know nothing about spine and what would possibly be affected by switching arrows or lengths. Could someone speculate as to what would be the best arrow for my setup? Keep in mind I'm pretty happy now...just looking for perfection. Thanks all.
