Mobo with the zapper and nap 360 rest would it not be easier to "fit" the fletching through with a staight off-set fletch? That is my thinking, I think
I don't think it would matter with blazers/2" fletchingbut if you were going to use 4" fletching then I would think the helical, especially an offset helical, would have unwanted contact.
