This is what I ended up with. A marked improvement over the stock caliper with SS line and EBC HH pads. It used to fade towards the end of a long stop, pull harder but get less effect. This has super feel and modulation, the power stays right to a dead stop too. I bet a mm or two bigger master might be even better but as is it is a true 2 finger brake.
It got a coat of black paint for now, blends right in. I figured the few other aluminum bits have cheap black paint anyway, looks decent enough.
