Kool-Stop thinline toe-in

A quick question about setting up my new Kool-Stop pads.

My previous brake pads have been flat, and I've toed them in by tightening them with a penny under the trailing edge to supply approximately 1mm of toe-in.

I just bought a set of Kool-Stop brake pads for my cantilevers. I noticed that the trailing edge of the pad protrudes a bit towards the rim.

How should I arrange the toe-in...or does that trailing edge jutting out of the pad take care of that for me? If I use the jutting trailing edge to base the toe-in on, the angle of the whole pad is rather extreme. If I use the area just forward of the protrusion, it seems to look normal, and the trailing edge doesn't quite contact. Looks right if this was a flat pad.

But, if I just square the pad on the rim, where leading edge and trailing edge both contact, then the main body of the pad does have a very very slight toe-in, provided I'm careful in tightening the bolt.

Thoughts, or experience with this particular pad?

The proof of the pudding is in the eating.

Stick them on however you like and make a test stop. If you get decent stopping power with no squeal, leave 'em be.

That's it, trial and error. My current kool-stops need to be toed *out* (front farther from rim than back), for whatever reason, to de-squeal.

Generally, these should be installed with the two ends hitting the rim at the same time. The bit at the back is intended to act as a "squeegee" to clean the rim before the main part of the pad engages.
