To the OP, I switched our former road tandem from BB-7 to Hy/Rd a short while before upgrading the whole bike to one with Di2 full hydraulic, so I have experience with a number of options. If you can fit the Hy/Rd without issues (I had to switch the rear rotor from 203mm to 200mm to make it fit... yes it was that close) I highly recommend them. The BB-7's weren't bad, but the Hy/Rds were noticably better.

Don't underestimate the importance of the self adjusting feature. BB-7s are at their optimal adjustment until the first time you use the brakes. I've had to adjust the pads mid-ride on routes with multiple long descents.

I modified both Hy/Rd lever arms to make them work better with the Campy levers on that bike which have a slightly shorter pull than some others.

The Shimano full hydraulic have eveneven be feel than the Hy-Rd, but I've found them to be noisier (Ice Text rotors vs Avid rotors, stock pads on both). I was very impressed by the Hy/Rds.
