Chaoctaw, I would suggest a Bitzenber jig with the standard 120 degree receiver. There is a notch on the receiver head to use as reference for the cock feather. I mark my arrows before jigging so specific lettering on the arrow is at the same point when I set the arrow in the jig. Should there be any difference in weight of each shaft they will all be the same when fletched. I shoot 3-4" left wing feathers with 3/32 right helical. Through years of experiment this seems to give me the best spin with the least amount of drag.
