We've had trouble with the Blazers from the standpoint of them sticking. Just seems like there is no glue on the shaft when the vanes fall off. We've been hearing of the Durovane Predators so just got a pack in yesterday. Haven't fletched any up yet but they are basically the same shape as the Blazer (slightly different rear shape) but also are just a tad thinner and feel more flexible. Anywhos I like the looks of them better and maybe will fletch some up this weekend to try.
