Offset will work, but I prefer a helical. I shoot both right and left wing feathers, and don't see any difference--just don't mix them on the same arrow. You can buy just the clamp for your jig. You won't have to change nock recievers--the different nock receiver is for fletching for a TM Hunter rest, with the cock feather down.

No problem on the questions--lots easier to ask than to spend a lot of extra money that you don't have to. Good luck!
