Hdot Verseman,
hay hands down i'd go with a Renzetti traveller's cam model ,also they have a separate midge jaw assembly you can get also,but i feel that's unnecessary.This vice set the standard for rotary vices when it was a thumbscrew model,now with a cam operated jaw its the Cat's meow.I personally tied for four shops locally here in the Lehigh Valley and Poconos and guided quite a bit.When i started tying for the shops and clients i had a Thompson 360 SLT rotary vice,although this wasn't a true rotary vice, so i got a order for one of my custom inlaid shadowbox frames with several full dress Salmon flies and a picture of the guy who ordered it with the fly the guy used to catch the Atlantic Salmon he caught on the Cascapedia.The fish was a monster and when he recieved the Frame with flies and picture he sent me a quite a nice tip as well as payment. I used the payment to buy my Renzetti Master Vice,and i have never looked back.
Renzetti hands down for rotary,and if you get a stationary vice a HMH Spartan is great as well.hope this helps.
