The Jo-Jan is great for people who are on a budget and who aren't sticklers about exact placement of their fletching, and who don't want oruse ahelical fletch. The Jo-Jan can be set for either straight or offset fletching. Like I said the Jo-Jan is not precise, the individual jigs do have some wobble.

I personally like the Bitzenberger, because I'm anal about my fletching placement and I use a helical fletch. I know that the Bitzenberger will fletch each arrow the exact same way, each and every time.

I hope this helps you.
