I spent over $40 to get in the 'supposed' super quiet/fast Tac 2.75" Driver vanes (vanes/glue/pen shipping), Levi Morgans super quiet vanes .. they SUCK to fletch, to put it bluntly .. btw, I have over 20 yrs fletching arrows for myself and customers .. Morgan and Lancaster Archery tout using their Tac vane Glue and primer pen, which I also purchased.. I went by the prescribed methods as shown in the vids by Morgan and Lancaster Archery .. I used a Grayling Jig/Right helical (similar to a Bitz) as my AZ Mini Max wont work with them... one out of three vanes, the rear REFUSED to stay down, or the whole vane refused to stick.. I used the methods as described ... didnt work .. I had previously read about fletching problems with these, they are a very thin base and 'slick' which is supposed to make them 'quiet' and faster in flight ... NOPE !! .. the damn things just wont stay down .. I use GT Velocity's and roughed up the shaft and wiped with Denatured alcohol as I always do with my Blazers, .. NOPE, still wont stick .. no wonder Morgan silenced the replies on his you tube vid ... I tossed the remainder in the trash .. never again // I then got in Goldtip Fusion 2.75" flo yellow vanes from Lancaster, and with these I can use my AZ Mini Max, and regular Pine Ridge glue which I use on my Blazers.. The GT Fusions are a wide base ... I used the AZ Mini Max, after roughing the shaft and using Denatured Alcohol to wipe down and just applied the glue .. those vanes fletched up wonderfully ( I did 6 arrows), and with the Mini Max left a fantastic Helical, no problems at all .... so if one is looking a a longer/lower Profile vane, I recommend the GT Fusions, stay clear of those damn Tac vanes .... good luck ..
