Flywheel lightening & performance gains from lighter flywheels

I'll probably look into getting a stock VX flywheel or whatever I can find cheapest. I don't see any harm in trying a VX flywheel. I doubt I'll go any lighter due to the cost of aftermarket, and I haven't seen any results indicating I could benefit with my driving style (steady speed highway).
Do we know what the weight of a flywheel on these cars is, exactly? I have heard that my DX probably has a 20 lb flywheel, but I don't know. How heavy is the VX or HX flywheel? Exedy lists flywheels for the sixth gen Si that run as light as 9.5 lbs and claims each pound is like take 50 lbs off the car (I don't believe it).

I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
