Jo-Jan Jig Question
 

I have a jo-jan fletching jig that I have owned for 25yrs or more I have a straight and right helical clamp and was wondering if the helical clamps have changed over the years? looks like the twist rate will be way to much for carbon shafts! I have been out of bow hunting for awhile and just got back into it so just wondering If anyone could tell me should I fletch helical or straight offset for broadheads on carbon shafts? I know most carbon arrows bought allready fletched are straight offset would I gain anything by going helical?

I put as much helical as i can get and still have good contact with the shaft. That has worked the best for me to stabilize the arrow quicker and tighten up my groups.
