I am also wondering if its the helical/6 degree offset I've got on my EZ fletch? Bazers recommends a 2 degree offset. Is the stiff vane going through the biscuit at more off an offset putting too much pressure on it?
This could be your problem right there.... You cannot get alot of offset or helical with blazers due to thier size.... If you put too much helical or offset on them they will not have good contact with the shaft.... Knock back your offset to 2 or 3 degree just you some to practice with to see where you can get the most offset with total fletching to shaft contact.....
