I am also a big feather user. I have used both gateway and truflight but have found truflights bases to be a bit more consistant. I also use feather fletching tape to fletch them. It is so much easier than waiting for glue to dry. And I have never had any problem with the tape coming undone. I just place a dab of glue at the front and the back, U have used feathers in every weather condition imaginable and had no problems at all. As far as them grouping the same with Blazers, they are very close. When I say very close I think my feather groups are about 1/2 inch higher if that. Not enough to be concerned about really.
