In answer to the original question, I'd opt for the top-of-the-line Dyna King. No particular reason.

Now I do have a comment about something previously said. The Thompson 'A' and 'Pro' vises were used for decades and they were excellent vises when they were first manufactured. There are many of those vises that are still being used. Individual vises were used for a wide range of hook sizes and for as many as 100,000 or more flies. Reminder - The head/jaws of these vises are controlled by a collet and lever.
