I have learned the art of turning nocks to get my arrows all flying in the same place while broadhead tuning but I don't really like having arrows where the cock vane isn't in the same place as the rest of the arrows. So, as I get ready to glue vanes on a set of bare shafts is there a procedure for figuring out the optimal location of the vanes to avoid this problem? I'm guessing shooting bare shafts won't give me any information to work with so is vane location simply a guessing game?
