Help me pimp my brakes - brake upgrade (calipers / pads)

cheers though, Dammit also recommended these. I just didn't know whether a set of calipers for £20 more than the blocks would provide more of an improvement than the block alone.

I've recently upgraded the blocks on one of my bikes and it's a revelation, the braking before was fine but not confidence building, now I can fly down descents without any nagging doubts about whether the brakes would stop me in an emergency.
