I bought mine when they first came out and tied everything from a 4/0 to a 26 with the standard jaws---I fealt like i needed a rotary so i bought a Dyna-King and sold it within a month---a couple years ago i tilted the head back to take a picture of the fly and it spit the first hook ever but it did chip the carbon steel jaws. I replaced the jaws and im still tying on it.
