Well, now that someone revived this, I feel ok posting. Voted BS, but I can't say as I'm a fanatic.
BS by a hair, then Cherry Blue. Topre and Cherry Browns after that, but Topre much more. Do not like Cherry Blacks, even though I have a few. The last time I used ALPS was in the 80s, so I'm not sure I should comment.
I do so miss my Model F+PC/AT, though, lost to time, storage, and relocation...
