Well, I could not vote! There was not a choice for what I do. I paper tune, but I use fletched arrows. All of my bows are almost the exact same poundage, so I know what arrows will be close when I start. I then shoot fletched arrows thru the paper and let the paper tell me how I need to adjust my nock height and spine (only one thing at a time though).
I paper tune from 6' and then from about 12'-15' to make sure all is good. After paper tuning, I put broadheads on my arrows and verify that the tune is what I want.
This method has worked very well for me over the years.
I will also add that a fairly consistent release is needed for the paper tuning to work well and give reliable results.
