yes, i have switched wheels.
ok... i seem to have fixed the problem with by messing with the high low screw in combination with that barrel adjuster thing. it's shifting good for now but this is just from shifting with the bike upside down (i don't have a workstand) so i dunno if real road shifting will be any different.
i will check that park tools and sheldon brown as well if i still get problems... or i'll swing by my LBS on friday.
thanks.
