IMN23D, first I want to say thanks for introducing us to the bearing test which I had never heard of but is right up my alley, I am a tinkerer. I picked up 3 bearings at a bearing shop yesterday and have been playing with it. My question is, when fletching for a single cam, prong type rest (actually I am using a dropaway) with release do you put the cock fletch on the weak or stiff side if the spine? Or is it mostly a matter of getting them all consistant?
