Thanks for all the helpful info. Does the lighter pedestal base on the Renzetti make the vise much more unstable?

I don't spin a lot of deer hair, but I do tie a lot of big clousers. I've never found the Renzetti Traveler to be unstable at all. Bottom line is that there isn't a pedestal base on the market that you can pull thread laterally and not make it slide.

If you are really leaning into your flies, then you should be using a clamp base as opposed to the pedestal.
