Having multiple "levels" of backup is always worthwhile, fdwlaw, so I think it's good that you're supplementing a clone with other techniques.
But I wonder why -- if you're updating your "home folder" backup every day -- you're not updating your SuperDuper! Smart Update (full) every day too. It doesn't take very long, and it means you'd recover even faster in the event of a problem.
