A lightweight flywheek is very subjective. Each driver is diffrent and has diffrent prefrences.
Yes, a lighter flywheels means less rotational weight. Yes, it will be noticable. You car will rev up easier, and faster. The nice thing about Spec, they also offer an additional lightweight option, that reduces the weight of the entire clutch assembley by ~22%. This will benefit the same way as a lightweight flywheel. Combine the two together, and you have a substantial weight savings over stock, with a strong clutch to go with it. Money well spent IMO.
However, not everyone likes a lighter flywheel. Just how it helps your revs go up faster, they will also go down faster. Your flywheel has less momentum and will slow down from a spin just as fast as it speeds up. This means longer times inbetween shifts may cause a drastic change in RPM. Hopefully you are good at revmatching to help keep a smooth ride. Some users report stalling if you rev high then throw it into neutral at a stop light. The RPMs fall too quickly from the car to compensate for it. This is a rare occasion, but still a possability to consider.
All in all, it might be a little tricky to drive in the beginning, but should be very easy to adapt to. Given a week or so of daily driving, you should be driving this like your car came with it.
