If I do make a spiral wrap, I whip the ends with a little thread, usually use a “modified Hybrid” feather, take about a 6″ full feather, using a straight fletcher, glue about the front 4″ on staright, leave the back loose, when the front sets up, glue and pull the tail end into an off set.Put on 3 feathers like this. This set up gets off the bow fast and starts spinning at about 30 yards to slow the shaft, you don’t sacrifice arrow speed.
