I have a fairly new 2005 Stumpjumper FSR with a 22/32/42 upfront matched to a 11-34 rear. The rear derailleur is a long cage XTR (this is the only non Deore/LX part on the bike - probably for eye candy marketing reasons since the XTR logo is very recognizable on the rear derailleur). I find the shifting to be fairly poor even while in tune. Maybe I'm to used to my road bike but there's always a slight lag in responsiveness. I'm guessing the problem is due to the long cage derailleur. So, question is, what rear cassette can I use that would accomodate a short (or at least shorter) cage derailleur. I like the 34 easy gear but could probably get away with a 32 no problem. The 11 is also probably overkill.
