I use a deore hydraulic, it's sweet as fuck, little lever is perfect for 1 finger braking and the servowave lever means the pads sit a little further from the disc which is nice when polo discs get bent so easily. They are about £40 from rose bikes with the option of a left hand lever as forruns are funny and use the wrong hands to brake. They apparently have the same power as SLX and XT but have Allen keys for adjustment instead of knobs, which is probably a bonus polowise. I'm thinking of putting them on my mtb instead of the hopes I have as they're that good.
