I've had a Peak rotary for a couple years, tied hundreds of flies on it and the thing hasn't let me down yet.
I rarely use the rotary feature. I honestly should use it more but by the time I remeber it's a rotary vise, I"ve already tied a few flies.
I do like the peak vise tough.
It's a pedstal model and the only thing I would change would be the rod should be about 3" longer but other than that, it's a great vise for the stuff I tie.
