I posted up some time back to see if anyone had heard about these fletches.
Well, I managed to buy the 1.6 parabolic and 2.9 shield cuts in, and so far, they have been working out great!
As with the old Plastifletch, there's no preperation involved save for ensuring that my shafts are clean. I just used a cyaoacralate glue and everything was all set.
Flight on my AXIS FMJs appear to be very straight in cross-winds, but the real test came when I deliberately torqued my release and ripped it to launch the arrow askew. The vanes corrected the flight very quickly at around 10-15 meters (by visual observation).
They also perform exceptionaly well in heavy rain. This was my best group shot at 76m in a storm.
Just wanted to share what I found in case you're looking for a fletch that may offer faster/better correction. I do not work for AAE and neither am I sponsored by them.
