I’ve been tying flies since late grade school and did start with a mini-vise grip. Gradually upgrading over the years.
The most notable rotary vise I had was a ‘Norvise’.(http://nor-vise.com/)..not cheap and being honest, for a lot of my work tying, it did NOT meet my needs. They do work some some folks, so see if you can ‘test-tye’ with one before you make the jump….
Just my .10$ worth.
