Well my new Workbench book (Lon Schleining) was in the mail today and I'm a bit overwhelmed at all the vise type choices for the bench ends. I'm going to hit that chapter pretty hard, but thought I'd see what folks opinions are here. I'm just in the research stages of a possible workbench build after my DC install gets wrapped up. This would be used mostly for small/medium furniture type projects. I do some Neander stuff already but would probably do more if I had a proper bench to do it on. The bench front choices aren't giving me any quandaries, just the ends.
Twin screw vises
What type's are better suited for what type of work? Is there a clear heirarchy of good/better/best or is each better suited to a particular purpose?
