Another vote for the Spyres from someone that wore out a set of HY/RDs. Unlike the BB7s, the Spyres are a clever dual piston design. Much easier to install and maintain than HY/RDs, and I find the power equivalent to those. A 3mm hex is all you need to adjust the pads for wear.
I do have a set of Juintech brakes waiting for when the Spyres give up the ghost, but the Spyres just keep on working.
