A bit windy, buy nothing severe..
Jennings T-master with a QAD drop away and pulling about 70 pounds.
Ihave Easton Axis St's, Carbon Vapors 4000, Carbon Vapor 3000, Easton LightSpeeds,I tried them all and noticed the same thing with each one, each arrow has various fletching, some are 2" Blazers and other 4".Again my groups are tight, paper tuning would tell me what I already know, they are leaving the bow in erratic form.
I am going to check out that link for tuning and see what I can learn as well, thanks.
