Whats so bad about disc brakes?
Don't say the fork isn't as comfy as a touring bike fork capable of carrying front panniers coz it ain't.
Good disc brakes(BB7's) stop very well indeed wet/mud or dry,with great modulation,don't wear out rims and keep on working even when the wheel is badly out of true so long as it'll go round without the frame stopping it
Bent rotors are the main claim of worriment,if you're that concerned carry a spare they're cheap(£10?) and weigh very little or,unless in Outer Mongolia,are available from almost any bike shop.Pads also last far longer than V or canti pads.
Did I mention they don't wear out rims?
