A.K. Best says that the best height for the vise is one where the arms can hang comfortably down from the shoulders, making it only necessary to raise the forearms. I've noticed at fly tying events where I will often tie for many hours at a stretch that this relationship is usually critical. At most tying events the typical chair seat to table top distance is guaranteed to quickly lead to the old pain-between-the-shoulder blades syndrome. At such events, I try to (and usually do) remember to bring along enough pillows/pads to raise my seating position to something approximating this ideal. At home, I usually tie at a rather high workbench and have found that either standing, or sitting on a rather tall barstool, works best for me.
