newf-Thanks! I couldn't figure out what it was I should be adjusting. I'll start fiddling with the stays posthaste, that rubbing is annoying!

nuthatch- My bike is a touring bike and built with plenty of clearance, the darn fenders just aren't on straight. They *ought* to fit. Glad to know I'm not the only one with finicky brakes! I was hoping having cantilevers would be *easier* to work with lol. What irks me is that I'll have it all perfect on the porch, then I go off for a ride and hear the shhhhhhh'ing if the brakes rubbing...
