I use an offset clamp on my jo jan for them and put a good amount of offset on the jig itself also. I do this out of habit from setting up arrows for 3D, where I have to get clearance for a wide line cutter shaft on a spring steel blade rest. Honestly you would think that they would fly better on a helical, however I don't see how they could fly any better than mine do right now. My 30X pros w/ blazers on an offset are what I used for the whole last part of this 3D season and even my paper target gamesat 30-40 yards are pretty impressive at least for me. I shot my slick tricks like this last year on a hunting shaft also and had no issues, I was able to shoot the same groups as a full helical 4" vanetec at 40 yards.
