Thanks a bunch, Mark. I plan to use the Kodak times for bleach/fix; they're about double what Rollei suggests -- six minute range.
And it sounds like circular agitation won't cause streaks during these steps.
As far as developing, is it as critical to tap the tank to release air bubbles on the film as it is with black and white? (Maybe I'm splitting hairs now. I've been reading about this stuff all week.)
