Just thought I'd update this thread in case someone else googles it up. I made the switch to a 7-speed 13–28 HG cassette plus a 36t sprocket and a SRAM 8-speed chain. To put it scientifically, I would say the drivetrain feels a bazillion times better. No more ghost shifting or chain skipping under load. The shift from the 28 to the 36 is just fine by my standards.
I'm afraid it wasn't a very scientific experiment—aside from the new chain and cassette I also switched the bottom bracket cable guide, which didn't look like it was guiding the cables very smoothly (unless two 20° bends are a good thing), so that could have been partly responsible for the ghost shifting. Anyway, I'm happy and I won't be going back to 9 speed anytime soon. The 'frankencassette' looks bizarre with 7 black sprockets and the silver 36t, but I can't see it when I'm riding, as they say.
