I have a Regal with a pedestal and clamp mounts so it can travel easily and i can use it in any situation i run into in those travels , the brass pedestal is a bit heavy to carry around with you so i switch to the clamp mount when i take it on the road. The Regal has what i call a semi rotary function that lets you easily rotate it enough to check out the bottom and the back of a fly if you want to make sure all is going well and looking good in the parts of the fly you can't see while tying with a fixed jaw vise like the Thompson A that i learned on and still have and still occasionally use or let someone use who wants to learn , on a trial basis before they make the big leap and invest in their own equipment. My feelings on a rotary is that pro tiers where speed comes into the picture are fine if that's what you want to do. For myself though speed is not a requirement , even if i'm tying to fill an order for someone , i want the experience to be relaxing and enjoyable , a sort of therapy. I feel tying is closer to art than manufacturing and cranking out dozens of clones is not what i want to do. I do it to feel good and what makes me feel good is creating a decent looking , durable imitation of something a fish might eat either to use myself or for someone else to use with success which is what i want , bottom line , for myself or a "customer". Speed and numbers are the advantages that a rotary gives a tier IMO and i'm not worried about speed and numbers. I just want to have fun. HAVE FUN!!!!!
