I just bought a Bitz jig with a RT helical clamp and fletched my 1st arrow fletched with feathers. I think it turned out GREAT. I used 4" Chartruese Barred Parabolic Trueflight feathers and Chartruese Onestringer arrowwraps. Im very impressed with the Bitz jig...Ive used a Grayling jig in the past and I bought a Bohning Blazer Helix jig about 2 yrs ago and It works GREAT for my 2" Blazers for my compound but it only fletches 2" vanes.I LOVE the Bitz jig for feathers, it put a super nice helical on my 4" feathers. Ill post a pic later.
