I understand the argument to simplify, and can totally relate to trying to keep on top of the maintenance. But even the thought of letting one or more the stable go is hard to wrap my mind around. I love riding each of them, they each have their own personality, and I can't say that there's any ONE bike that is better than, or could replace any of the others. Could I if I HAD to? Sure. But until that time comes ... it'll be N-0 for me.
Very glad both of your bikes went to good homes.
