I wont comment on hydraulics but I think Eddy, Philip shadowman and Emyr uses them. Can't really recall any other names ATM. Eddy is running SRAM/AVID XO with internal routed hose, Philip I think is running Saints again with internal routing and Emyr is running XTR with external routing.
As for mechanical disc, yes BB7 is considered the best but they are not immortal. The red adjusting cone on the outside can come loose and fall off and they are quite fiddly made. Also there is a misconception that the BB7 has two moving pads but this is not the case - it has two adjustable pads but only one actuation arm. Only the outside pad moves when the cable is pulled and the inner pad is static but you can adjust it as it wears to get it closer to the rotor. Hence BB7 ≠ Dual moving pad brakes.
This is a bit of uncharted waters but I am going to give the TRP Spyre Disc a try. It is more compact than the BB7, less fiddly and generally looks better made. Lots of good reviews at the bottom of the page but alas nothing in relation to polo of course. They are short pull which means that paired with a conventional v brake lever will give you a sharper stop but I will counter that with a adjustable lever (I chose the DX, the Avid SD is another option) to enable me to choose my preferred settings. Nice price too at 64 quid for front and rear.
There is also another TRP disc that I am keeping an eye on, the HY/RD which at 100 quid for front or rear isn't really cheap. The reservoir is at the caliper (gulps...) and there is no hose but instead it is actuated by a cable (yay!). Quite a few nifty features too like self centering pads and a lock-out option when you are adjusting them. Again untested for polo but I would love to give one a try when I have the cash.
Hope this helps pajac.
