I have found even on the ez fletch to keep glue off of the arms apply vasaline to the arms before you but the vanes in the slots it will keep glue from building up on the arms and you will not have to scrap it just about every 3 arrows you fletch wipe off the vasaline and reapply. I also have never had a problem with the vanes slidding around in the arms but you do have to make sure they are pushed all the way down though. Pay attention and it will work out fine for you.
