I am currently using 3 5.5" helical feathers. I was thinking of using 4 5" feathers. If I do this can I put them helical or straight? What setting do I use on my Bitz jig? Thanks

By the way ,any 4 fletch pics?

The second or third setting and helical is how I do it.

helical

Some like 75x105 (I do) and some like the 90... can't say there's a difference.

I like 75x105 or 60x120 better than 90.

I shoot 4 5" at 90 degrees helical. I started shooting 4 fletch back in 1969 and have been shooting them ever since.

I'm going back to 4fletch using 75x105 with 5.5" nana's.

I shoot 4@4" shield cut and I love em' you dont have to look to see if you have your arrow nocked properly(3 fletch).

I like 4  5"  high profile shields @ 90 degrees.  I put as much helical as the JoJan will handle.  Love the way they fly.

i use the 90 (middle screw) setting on the bitz with 4 5" feathers. very very accurate....!

Same here, went overboard and tapered them too, only have three of five left, Robin'd them
