I'm getting my Surly Cross Check soon, I'm looking at brake options. My LBS, who will probably sell & build it, didn't even consider the question, I was talking about Ultegra, so I think they're assumming canti. I'm a fan of v-brakes, from loaded touring in the Loire Valley to this morning's muddy rocky descent in the Dublin Mountains.
I've never used cantis. I haven't read a lot of good about them, and I've seen negative remarks about their stopping power. I'm over 200lbs and will be using the bike for loaded touring, we're talking a total package near the 300lbs mark (I'm not sure which side of it ).
Can cantis do the job for me, or do I need to ask them to swap? Will it cost more?
