This is the best video because it's the ONLY video out of 10 or so I've watched that even mentions the index / cock vane (which I find bonkers because it's so important!). Sadly, the one thing you don't mention, is which side (looking from the back) do you put the sticky tape on for fletching after the ink/paint has dried? Since you 'draw' on the 'right' (again looking from the back) do you then apply to the fletch to the left of the paint? I've re-done a single arrow 3 times to try and figure out the rotation, but each time I feel like my fletches are wildly out of alignment with the nock.

Can the Beiter Try Liner be used to have a left or right offset for helical fletching?
