yup! they're great! I used to have them on an old higher end scwhinn road bike a few years back in 8 speed and they worked great. I just ordered and received, although have not yet installed, microshift STI shifters for use on my commuter, paired with a shimano 9 speed drivetrain.

if you are using the integrated STI shifters, I think you will like them. they have a slightly different actuation than standard shimano or sram, with a seperate button for downshifting, but I actually like it, very easy to use. Also, the form factor of the brifters is very comfortable to my hand, similar to shimano. their components are well made IMO, and they will certainly be better than the vintage stuff. the fit and finish is nice, and the price is right. go for it!
