I have shot straight fletched arrows for the past 10 years. I'm looking at the helical options but got confused over the terms. Have heard "offset" "2 degree helical" and "6 degree helical". I understand with a screw inbroadhead that you need right helical. Question is which is better for a whisker biscuit rest? How and where do you get a good jig for the different degrees of helical. (Bitz seems to only come in right or left, no indication of degrees)

You in the know, where do I go??

Thanks Jim. After your description and looking at my jig, I thing I've got it figured out.
