Buckmister, I also recommend the Bitzenberger.

If you purchase the straight clamped Bitz, you can still offset the fletch which will work similiarly to a helical....

Now a helical is when the fletch wraps around the shaft of the arrow at an angle to the arrow, to what degree is determined by the fletch jig....

A offset fletch is a straight fletch slightly turn off center to the shaft.

A helical will get the arrow spining sooner and faster out of the bow which is a key to help stabilize broadhead flight. An offset fletch will get the arrow spining quicker as well but not quite what a helical do.

You can buy straight, right or left helical clamps for a Bitzenberger Jig.
