I have used the A&A fletch exclusively with UFOC/UEFOC arrows and single bevel broadheads for the past 3 years. The shorter ones with a turbulator work very well and are dead silent. They also tolerate a lot of moisture and still fly like darts.
The first ones are 2 3/4″, the second are 2 1/4″, the last ones which I use now are only 2″ but in a 4 fletch.
these are with tuned FOC arrows with broadheads on from 20 yards
