Good to know about the MkII GT not having enough travel to move over a modern cassette (I don't know if you remember, but I have one; at one point you were interested in buying it I think). I stand by my recommendation of the other derailleurs I mentioned, though..............As for the overall width of nine speed and eight speed cassettes, they're the same; the nine speed just has more gears crammed on there. That's the reason nine speed chains are narrower-
