Lightened flywheel question

[kasey200x]

I have a few fly wheel's from all my donor engines and found this one. Almost all of them are designed differently,, from the holes drilled in them to the magnets on them. But this one has a plate on the back. The total widgth of this flywheel is the same as the others. But it has this plate. Is it made to take up the space of one that has been turned down?
Is a lightened flywheel worth being put on a 200x?
Thanks

i was wondering what the pro's and con's to the lighten fly wheel is myself, i spotted one before for the 200x but i didnt know whats the gains were so i passed on it.

I know the gains are basically better throttle response. It's less mass to get turning, so it's easier to get it going. But that also means is has less momentum. So i guess it would have to work harder?

generally speaking, it should rev faster. and when you try and lug the motor down, it will have alot harder time staying running
