Jamesdak ~ Those are some very nice bikes, but I've never ridden any of those brands. I entered my first mini triathlon in circa '84 and rode the mystery Serotta in about '99. Fifteen years on Aluminum made the steel seem all the better and, having spent most of my years in uniform stationed overseas, I'm sticking with American Made.
On the other hand, my user name should give away that the LeMond in your stable also has a special place on my list. The mental picture I have of GL putting it to Fignon in the final individual time trial, in the '89 TdF, is the one I've used [many times] to get me through the tough rides.
