Over the years of working with fletching, the one thing I can tell you for sure. When you use a single fletching jig for all arrows, every arrow out of it will be the same. When using the JoJan, you have six different jigs, thus six different fletch orientations. Now mind you,,,,and short distances,,,,very few can shoot well enough to see that difference with traditional equipment. But for long range, dot drilling accuracy,,,it makes a huge difference. I have a blitzenburger that I purchase in 1966 and use it to fletch every arrow I own. I also have 3 JoJan jigs for mass production for the shop. Just knowing that every arrow is the same, takes a lot of guess work out of the equipment set up.
