I fitted a roller-bearing last time, and after a few thousand miles it has
started 'wittering' just as I take up the free play. I don't know what I
was thinking of. Did I really think I would leave that bearing in the next
time I change the clutch? Of course not. Do carbon release bearing
regularly wear out before the clutch needs replacing anyway? Of course not.
Would I fit another one? Of course not.

Purely anecdotally (no personal experience), but I have heard from
several sources that the roller throw out bearing is more prone to
trouble than the original style. This seems to be contrary to your
experience. Possibly it's a question of increased complexity -- more
moving parts means it's more likely something could go wrong, or have
been assembled incorrectly in the first place. At any rate, clutch
components are no place to take risks, as the replacement process is so
arduous, so it behooves one to be very, very sure before making changes.
My 2¢, YMMV, etc.
