Sants dropped a Renzetti Traveler Rotary on my Fly Tying table for Xmas and I just love it. Like Steve said, it is much easier onthe neck and I can tie 18 t0 3/0 and have done it a lot easier with the rotary feature. I believe the Dyna King is equal in quality and features but the Traveler and yhe price was right--free from santa.
