I don't think there's anything wrong with what ya got...my size suggestion sounds good, if I say so myself.
There is no "next size up" in this context. That would relate to rotor diameter (ie: going from 160 to 180) and not thickness of the braking surface.
As to that, the minimum cross-sectional thickness of the rotor brake swept area is .15" If the rotor is thinner than that it should be replaced (just like on your car. Too thin = worn out). At this point I'm just wondering if there is a benefit to be had from going to metal pads and a different rotor. Shimano has several different types. Perhaps an aftermarket rotor/pad setup would give better erformance on those long downhills where the brake heats up a bit after a few miles.
Plus, I have a slightly warped rear rotor which should be replaced anyway. And, it's time to change the pads.
So, are there other options I should be thinking about other than just staying with the resin pads?
