I'll adress a couple of comments....
1. If they are making noise after changing wheels you have a brake pad/rim incompatibility. IIRC open 4CD's have dark sidewalls? You may need to change brake pads or get rid of the color on the rim sidewalls.
2. If the have more 'brake cable feel' well, thats not a problem with the brakes per say its a problem with the cable.
I've set up and adjusted hundreds and hundreds of these brakes. They're not difficult to do you just need to know how to do it. Remember, your dealing with a how many decades old design? Of course modern brakes may work better or be easier to adjust. Isnt that what time and technology is all about?
