I've got 2 EZ (both are straight) fletchers and I think they are great for vanes. I coat mine with bow wax, to keep the glue from sticking to it. Also after I put the cap on it (while it's drying). I turn the arrow upside down (nock up). I do this because if the glue drips down the arm, to where it pivits, it'll glue it together. This happened to me and I sent it back to the company and they replaced it (good customer service). I can do a 1/2 dozen arrows in a half hour with the two I have.

I don't really like this jig for feathers as they are difficult to get loaded into the arms, and because of the curve of the feather, they don't want to stay in the arm (at the ends). The Bitz is a great jig for both but you have to do each feather or vane, so it takes longer.

I don't think you can go wrong with either. Have fun.
