I would think if your nocks are adjustable it wouldn't matter how your jig is set, just glue on a feather, after glue is set, pull arrow from jig, spin it over and replace it in jig and feathers should be 180 degrees. Then index the nock where you want it.

I just ordered some arrows. Gonna give this 2 fletch thing a try!

Well you all have talked me into it!  I know my arrows shoot fine with 3-3" so 2-5" would still give me an extra inch of steering.  Just got to let the last coat of poly dry.

I am going to give it a try.  I have some new shafts that bareshaft tuned pretty well.  I few years ago at a 3D shoot one of my feathers was shot off.  I shot the arrow with 2 feathers for the heck of it and it seemed to fly about the same as when it was 3 fletched.

Exactly old_goat2 or set your Bitz to 90/90 (four fletch) and rotate 180 for the opposing fletch.

I also turbulate my arrows which is a band (cap wrap material) ~ 1/16" wide and a few thousandths high in profile, about 1/4" in front of the fletching.  This turbulates the air flow just in front of the fletching and allows laminar air flow to occur over the fletches thereby making them more efficient i.e. smooth/consistent air flow acting on the surface of the fletch.  

None of this is my idea but from Dr. Ed Ashby's/O.L. Adcock from his A&A article.  Cool stuff.  These concepts are used throughout the aerospace industry.  Try it to potentially improve the arrow flight with any fletch size and configuration.
