Cantilever Decision: Shimano or IRD?

I am thinking of building up a cross-ish commuter bike with some parts I have laying around. However, I do not have any cantilever brakes and have never used them before.

After doing some research I am trying to decide between these two:

Shimano BR-R550:


IRD Cafam:


Any input or suggestions?
I like the look of the IRDs much more, but from pictures it looks as if the Shimano ones have a little nicer finish.
But what are the advantages/disadvantages of the two different designs?

The first thing to understand about cantis is the effect of the 3 different lever arm geometries available. Read: https://www.sheldonbrown.com/cantilever-geometry.html

Thanks for the replies so far everyone. The Sheldon article was immensely helpful, as always.

The TRPs are much too expensive for this project, but thanks for the link. I will check out the Tektros too, thanks!

Tektro orynx are also fine canti's, don't stick out as much as the 720's (which can be a problem in the rear), and they're super cheap. I got 'em on 2 bikes.

I have Ird's on 2 of my cross bikes. Love them! One bike has a 720 in the front and CAFAM for the rear and my SS has both IRD's.

Those are strange looking. I have Avid Shorty 6 on my crosscheck, and I bought the TRP Eurox (at a super great price) for my in the works Litespeed. Do I need them? Probably not. But like I said, they look cool

Ive got a set of Scott-Petersen SE on my loaded touring bike , work quite well..

In the frame build shop happened to have bosses which have a ring around them like Saturn , the planet.
as friction is the way the core fits on the Boss, this works fine. there is no spring anchor,
the return spring is a coil in each caliper, hence the look, form follows function.
fussed over the setup with spacers from rear axles , and some star washers.

It, the bikes frame, is made of substantial material . Much heavier than most people will accept. but there is no winding up the frame tubes as you grab the brakes,
like happens with thinwall tubesets.
I can bring the loaded bike to a stop, down hills, from the Hoods of the Modolo Levers,
I use cable out the top sort.

Unless you want to be able to stop. I had a set on my old Haro CXR; even with Kool-Stops, they were nearly useless. Plus, they were hard to center.

Right now, I'm running some wide-profile Kores that came off a new bike; I found them on eBay for like $20 or $30. They blow the Oryxes out of the water, plus they have serious mud-clearance. Maybe overkill for this build, but if the price is right...

I stop just fine on mine, they were on both of my racing rigs.

Everyone I know who's run them has had problems. Is your setup radically different from most? I can't imagine we're ALL doing it wrong.

Bear in mind, I say "nearly useless" in comparison to a dual-pivot road caliper with Kool-Stops and Nokon housing, which is what I run on my other bike. I know cantis are always weaker, but the difference was mind-blowing. I raced 2 seasons on Oryxes without dying, but I wouldn't recommend them to anyone who's building a bike up from scratch and has a choice (instead of getting them from an OEM).
