The TRP Hy/Rd list price $125, but it's easy to find them on sale for $100. The Hy/Rd does't require any changes to brifters, drivetrain or rotors. You have to decide if $200 per tandem is a "big nut" for significantly better braking and ease of use. I use full hydraulic brakes (Shimano R785, Shimano XTR, Hayes Stroker Trail) on several bikes and the Hy/Rd is reasonably close in performance. We would do steep descents on the Hy/Rd, but not on the BB7.

You're right that full hydraulic brakes require more expensive changes and are probably more suitable for new tandems rather than retrofits.
