You guys all have great responses so far. We are getting scientific....I LOVE IT!

I will say this. The wheels I had built for my track bike are ALOT heavier than the current wheels on my road bike. I have been using my track bike in replacement of my road bike until I figure out which way I will go with the new wheels. That being said, I can notice a pretty big difference in the wheel weights. Hillclimbing sucks on my track bike with the heavy wheels, but, the momentum on flats is great! I can DEFINITELY notice the difference between the way each wheel rpm's. Im not sure if I would want wheels that heavy on my road rig, BUT, I believe the wheels I was wanting to build for my road bike(SL42 rims, Dura Ace hubs, 32h, etc) are still going to be lighter than the wheels on my track bike. So it may be a good median. But I can somewhat agree that maybe the build I want to go with would be a LITTLE overkill for my road bike.
