Some context for Howard's post- he weighs roughly the same as a packet of crisps. I am ~80kg and there's no way I'd choose (road) cable discs over hydro, unless I was crossing Africa unsupported or similar.
Aye, I'm ~90kg (although I hope that'll come down) so I think I will be going for hydro. Are there any non-fugly hoods that don't cost the earth for a hydro set up?
Cable brakes are fine and pretty sensible for endurance bikes - wouldn't sweat not going full hydro. Certainly wouldn't consider a used hydro setup.
