Seriously, I'm seeing quite a few posts like this. In your case, as an owner of a 12 lb. bike, it seems you would prefer a more comfortable bike with less stiffness. In the hi-ten thread, someone says they like their hi ten bike more than a far lighter cromoly bike. And then there is the bikesdirect vs. $4K cannondale comparison, where the $400 bikesdirect bike is faster.

There are just too many examples of this to ignore.

My own bike, I preferred to a "racing bike" which was easily a lb or two lighter at the same price point. I found the endurance geometry not only more comfortable but far better for power transfer.

I'm still tempted to buy lighter wheels, but am skeptical of performance gains after reading these various threads.

I can state for a fact that I saw a huge performance gain when swapping out tires from stock to high performance michelins.
