"No offense, but this is simply not true. No matter how you or anyone set-up canti's you will never have as long a lever arm as linear pull brakes provide, it's impossible. No matter how straight you make the cable yoke, you can't change the fact that the more you pull in the cable while braking, the less leverage you have to brake, again physics get is the way.
If your a light person and your touring rig is light and your into the retro look, fine, but for a new build it makes no sense to use anything other than linear pull or disc brakes. "
Wrong, at least for drops. The brakes have a better lever, the levers have a worse, one, and from the hoods the fingers have a worse one. There are three to four components in the train: Hands, levers, travel agents if you like kluges on your bike, and the brakes. Linears win one, loose on three. On MTBs with flat bars not an issue but with drops it's worse with the overall result being pretty much indistinguishable performance differences.
