both the chucks you suggest will be fine. I don't like the "gear"
that Nova uses, I prefer chucks that tighten with an allen wrench -
the gear type tends to cam out and wear, it's much hardter to make it
really tight if you need to. My chuck of choice is a different brand
than those two, key consideration though was tightening via an allen
wrench not a bevled gear. (yes, I also have a Nova, use it for
smaller stuff)

The current SuperNova 2 uses just such a method. Much nicer and easier
to engage than the old SuperNova.
