"that just about any fly can be tied on a regular vise, however much more efficiently on the in-line."


Just for the record as I think you have a (common) misconception here. There are certain flies that will be tied more efficiently on an inline but not all and not even most. It doesn't help with many flies aside from being able to rotate just to view the other side (which a regular rotary will do).

Just wanted to point this out because if you get an inline vise thinking it will be handy for all your flies you will be disappointed.

FWIW I tie on a Norlander and adore it.
