To be honest, ifgoing for the S2R, I'd consider getting the supplying dealer to source a pair of 4 pad calipers ( at cost or less of course! ) as part of the deal thus protecting your warranty nad giving you the brakes you're used to!
Celeste is using her 900s monster as a benchmark which I think is a fair comparison.
