Discs aren't hard to bleed at all. Play with the linked brake system on a Honda motorcycle sometime if you want to have real fun. Also,discs don't have more stopping power than V's,they just work better in bad weather,don't wear rims,and require less futzing. Hydros require zero adjustments,just pad replacement and bleeding every few years. Cable rim brakes require adjustments for pad wear,cable stretch,and the cables themselves need periodic maintenance and replacement.
