I am looking to replace the Tektro Oryx cantis on my Cross Check. Does anyone have suggestions on a good cantilever brake for this application? Right now I am leaning towards the Shimano 550, but I'd love to know if anyone's found a better one.

I probably will not go with Avid Shortys - they are strong and I like their aesthetics, but I had them on a Kona a couple of years ago and I could never get them to stop squealing.

Let me know if you have any suggestions. Also I'm curious if I would get measurably better performance from using a straddle cable with a wide carrier instead of using a link wire set-up.

Any suggestions would be appreciated.
