I use an Arizona Ezee Fletch for carbon arrows with a 6 degree offset and have had no problem with my Blazers and the Wisker Bisquits. With a well tuned bow, it will group better than these old eyes can shoot! I also have never had to replace a Blazer because of wear in the WB. As long as you prep the shaft correctly before glueing the fletching on, you will have no problems at all. Just make sure that if you use a WB it has a large hole and doesn't grasp the shaft.
