At 205#, all this weight weenie talk sounds like science fiction to me. Everything I use is chosen for durability, especially the wheels, (36 spoke Open Pro Mavics).
Unless you're climbing, a few ounces doesn't make much difference to most of us. One of the better climbers in my club has several bikes, he has a 15 pound C-50 and a 28 pound Rivendell Atlantis. He still drops most of us regardless of which bike he is on.
