On second thought, I had one little "issue" with both of mine. Tried some of those FOB plastic arifoil things. To my surprise, it hits the fork of the rest near the bottom. I guess the "tines" of the fork get out of the way quick enough so that there is no problem with the Blazers - or any other regular fletching - when oriented so the cock vein is up. You can hear the plastic FOB hit and it pulls the moleskin up from the fork a little. I'm using the shorter fork - but, because of insufficient vertical adjustment, could not use the longer fork even if I wanted to change my setup to work with the FOB's. No big deal. Was just playing anyway.
