I am currently tying on the dynaking pro and the sidewinder. As as small time commercial tier the sidewinder has served me well. Like JC mentioned it is bulky, I've gotten used to it and love it for what I am doing. I use the pro for everything else.

If you are interested in EITHER of these two vises I know of two forsale at quite cheap. A buddy of mine, also a commercial tier is done tying and is selling both. Drop me a line if you want.
