I have both versions and love them both. The original was a little rough but smoothed up with use. The newer version is much better, smoother out of the box and cam lock jaws a big improvement over the first version. I also have a danvise and much prefer the mayfly vise, especially when tying smaller flies, size 10 or smaller. I struggled with the Danvise with my material hand and placing material onto hook, the angle on the Danvise just didn't work for me. Where the Danvise excells for me is in tying streamers especially when you convert it to straight jaws, an easy mod.
