cheers for that.
i'm not too picky, and i have all the bits, so it would be a just matter of a wasted afteroon if it didn't work! certainly the sheldon brown method won't work: i'd rather buy a new hub than new shifters (and bite the bullet and learn how to build wheels).
From what i understand, you think i could just change the shifters and leave the 7 speed cassette, chain and all. did i get the right end of the stick?
"Personally, I've never been satisfied with that but YMMV." i'd be really interested to know what went wrong when you tried, if it's a matter of slow shifting for example, i'd be happier than with the grip shifters (i hate those things, they give me blisters)
