Jup, I wouldn't attempt to advise what brand of bike to choose. You're experienced and knowledgeable enough for that, but I would question the idea of making a committed choice ten years in advance.
So many things can change in that time. Hell I wouldn't even put it past our government to pass an expropriation bill empowering them to take our bikes without compensation!
Seriously, I would consider making your decision somewhat closer to your retirement date.
