I use Blitz jigs, however I use straight clamps.

If I recall correctly, a Blitz right helical clamp is suppose to give you up to 6-degree max, but that 3 to 4-degree max is the safe norm that some helical shooters that use the Blitz say they get. If you' re using 5" fletch, 3-4-degree should do the job.

Remember; depending on type of rest your using, with helical you' re going to have some clearance problems. The greater the degree of helical, and height of fletch, the greater the clearance problem.
