Pulley systems, what are they good for and worth the money?

Well this is a fun thread. Reducing rotating mass will always help acceleration. Reducing it off the engine is most beneficial as the gearing of the gearbox and diff multiply the effect. I cbf looking up the exact math and gearbox ratios but I doubt you would notice much difference in anything but free rev and first gear acceleration. For performance I personally think your money is better spent elsewhere. If you want to tart up your engine bay then go for it, any damage to the bearings is unlikely to show up for years for the average driver.

I was having a dig at your incorrect grammar/spelling. "Be where" when it should have been "beware". Nice to see you corrected that.

No worries and I hate the auto correct on the tablet

I was always under the assumption that reducing rotational mass on the engine was more aimed at getting the revs to drop faster. I know a few of my older (non-performance) cars, it would seem like the red would just hang and hang. A lot of people were reporting that a lightend flywheel was the best way to resolve the issue. Now, I could be completely wrong by this way of thinking...
