I scraped up some funds to get another fix for my upgraditis. I'm torn between the disc/wheelset or going to 9spd drivetrain. Looking at a set of Mavic 317/XT hubs and Avid mech's (the mud & slop here in the northeast has been horrible this year.) Also in need of (wanting ) a new XT splined crankset, cassette & shifters to go 9spd. Just curious what you would do first & why. I like the idea of getting much better braking and significant decrease in wheelset weight in one shot for about $350. There's no reason the 8spd won't hold out 'til winter ...and I think I just answered my own question.
