It’s true, wheel weight by itself doesn’t give you much info. Where is the weight? A lighter wheel with less mass in the middle isn’t going to do much for you, if I understand. And then you have the tires, which are 20 lbs by themselves, and at the edge of the rotating mass. Sure 20 lbs vs 30, 20 will likely be better, but a lot 2 lbs difference?
