Hi nightwing, good to hear from you. I haven't bought the P220 yet, but will get it soon enough. I have ridden the carb P220 and found the rear brakes to be decent. As it is, I am not some MotoGP racer out on the road, so, whatever is available is good enough for me, generally.
As for your query, I won't really be able to help you much. Bandhav would be the right and apt guy to guide you more suitably regarding this.
Thanks,
-Aryan.
