Wish I could help, but... I only had one Grayling jig and only tried to fletch one arrow with it before I boxed it up and sent it back for a refund. "Cheap" is one word I'd use to describe it. I've got other words to use for it, but since this is a family site...

Find someone you don't like very much and pawn it off on them. A decent and relatively inexpensive jig is the BPE. Better is the Jo-Jan. Best is the Bitzenberger.
