I've got Brembo HC Discs, Greenstuff Pads and Goodridge Lines on the 172 and I can't fault them, then again i'm not mad brake hammerer but i've never got them to fade yet. The goodridge lines especially improve the feel when you get them hot hot hot, no squidegy pedal at all.
I'd have gone for DS2500s but I don't think i'd get the extra out of them for the cost.
