I just got my arrows in GT 5575 now what to fletch them in ? with a 3 blade broadhead (sonic 100 gr) set 3 vanes perfectly in line with the baldes of the broadhead; but with a 4 blade broadhead (slick trick) do you still fletch with 3 vanes or go to 4 vanes to keep the broadhead in line with the fletch? but what style of fletch to use is the delema?.
