I use both the Supanova and Vicmarc chucks and find them both excellent,
although to tighten the Supanova you will be turning the chuck key
anti-clockwise to tighten it and that may feel odd.

Well, it "tightens" on a mortise when turned clockwise. Of course the left
end of your grinder and the nut on the arbor of your left tilt tablesaw,
etc. tighten that way too.

"Lefty Lucy doesn't spread 'em for Chuck" is a useful NOVA mnemonic.
