I am still recovering from a flu from hell picked up in Spain ...but on the bright side...stopped in Plymouth England and had the chance to work the new Snowbee-Waldron Vice with it's very neet tube set-up...making tube flies just got a whole lot easier and more sensible......they also have very unique adapters for normal clamp jaw vices using the same principles...
I have been using the Vosler vice..sensational but not a tube adapter.
Check them out on their web site
These adapters have adjustments on them...awesome!
