OK, you want a ride report, I give you a ride report.
OH HELL YEAH!!!
Acceleration is improved, braking is improved but the flick-ability is greatly improved. Feels like I lost about 50 pounds off the bike. Amazing how loosing roughly 3.7 pounds of unsprung rotational weight can improve the performance.
If you've been on the fence about changing to a lighter wheel; DO IT!! (Legal disclaimer: YMMV)
Your test is a good one because (if I intrepret your initial post correctly) you actually transferred your previous tires to the new wheels, so the only change is the lighter wheels. New tires almost always feel better and it can be hard to uncouple the new tire feeling from the new wheel feeling.
