How long to get used to a rotary vise?

[rainbowchaser]

The batch of gear I bought recently included an Oddyssy vice. Never having used a rotary vice I thought I would try it. The vice rotated away while I was putting the hook in leaving a booby trap in the carpet. Things didn't get any better after that. The arm was in the way when I tried to tie off material that was put on using the rotary feature and I had way to much thread out from putting the bobbin in the cradle. I did manage two fishable wooly buggers which is about as good as I ever do. The second one looked a little better so maybe I can learn. How long does it take to get accustomed to one of these. Should I just admit that I'm a dinosaur who can only use a fixed vise?
