I got so frustrated with messing with the Bitz trying to get full vane contact with a helical clamp that I just sold it and have been using a AZ mini fletch. So far, I really like that thing!In reality, all vanes applied at any angle other than perfectly parallel to the shaft will twist around the arrow when properly applied and would therefor benefit from a Helical jig that pre-twists the vane to match the changing surface plane of the arrow at the front of the vane versus the back. The problem with the Bitz helical jig is that you have to figure out how much "offset" to use so that the helical jig makes good contact with the shaft all the way from the front of the vane to the back of the vane. That is dependent on your arrow shaft diameter, and there's only ONE specific "offset" setting that allows the helical jig to work properly. Any other offset and you won't get good contact between fletch and shaft all along the fletch. Any even when you get the correct offset figured out for your specific shaft, you won't have any idea what the actual degree of angle is unless you take some accurate measurements and do the trigonometry.
Personally I got super frustrated at not being able to explore DIFFERENT helical angles with my bitzenberger so I made a set of 3D printed adapters that allow me to use my straight Bitz clamp to apply vanes at any helical or offset angle I want. See this thread for more info or just PM me if you're interested.
WTS - Adapter for Helical Fletching at Any Angle With Straight Bitzenberger Jig
I recently got frustrated with the lack of any 3 degree left helical fletching jig, so I made this set of adapters for my Bitzenberger Straight jig that enables perfectly accurate fletching at any specific degree of right or left angle, from 3 degree helical to completely straight. The set...

It's the way the strings are twisted/strung . My bows turn left bare shaft. I've got the max amount of helical to the right I can do on my bitz (had planned on IW single bevels) but have also done some lefts. They group in the same spot as the rights. (Also using a v3 and rx4 for the testing)
Yeah I’ve heard this about the string twist as well but my old ABB strings twist the same direction as these Factory Zebras. I’ll have to pull up that video. Thanks
That's helpful. Thanks.

I think your question is how to adjust the setting on the Bitz; NOT if you should match the helical to the spin of your bare shafts correct? If so; you don't need to offset the settings on the top and bottom of the jig; the helical is already built into the shape of the clamp you are using (left helical). Those adjustable knobs are for adding an offset when you are using a straight clamp on the Bitz. Typically an "offset" is 1-3 degrees and a "helical" is more than that (3+). I have found that an offset with a straight clamp works pretty good on larger diameter shafts; but when you go skinny its hard to get vane contact for the full length of the vane. That is where the helical clamp shines. All this being said; you may need to adjust those knobs slightly even for a helical clamp to get the best vane contact for differing arrow diameters; even though you don't need them (nor are they intended) to do an offset. You can also slide the vane closer or farther from the nock in the clamp to get better contact. After i find a setting that works good; i mark with pencil on the jig to "save" my settings.
