IMO, mechanical discs are not good. the pads wear and then feel spongy or worse. hydraulics or bust, for me. (there is enough wear during a single cross race that mechanicals decrease in braking power, noticeably.)

anyway, is racing an element of your life, still? (don't mean this to come off in any way other than an honest question--just can't remember if you are still actively racing.)

you willing to take the aero penalty of discs?

i can think of one occasion where i would have liked more power (in a race), but i looked around and felt pretty happy that we all had equally little power.....so there were no sudden movements.

i hope disc brakes do not become a thing in road racing. say goodbye to neutral wheels that actually work w/o brake rub!
