I have tied with about 10 vises over the last 35 plus years starting with the old thompson vise and now for the last several years have been tying with a Barracuda that I modified'
I tye using a c-clamp with the vise inverted, ie vise down. found it very good.
Also still have the Thompson vise,a Traveler and the Squire.
Had a McKenzie which I sold and bought the Barrcuda, good exchange in my opinion.
