If you go the mini V route, be aware they're not all the same, the length seems to vary between 85 - 95mm and the longer the arm the more cable pull required. There was an online list, but the link I have is dead. I had some Shimano Sora ones (90mm arms) with Campag 10 speed levers, they worked fine but did need to be kept close to the rim. Used with 32mm tyres and guards, though I can't remember if the maximum tyre size was dictated by the brake.
I've had mixed results with canti's, the only ones I really haven't liked were the Tektro Oryx. The wide ones that stick out, like the Tektro CR720, offer loads of clearance, but are the least powerful. The mid profile ones, like some Shimano and the bling Paul Components Touring, are IMO as good as a mini V.
