Lightest Grips...Also Leather question

[Power Game]

I know that Babolat VS overgrips are the thinnest and the Head Softtac replacement grips are the thinnest. But what are the lightest grips, I'd assume babolat VS overgrips are the lightest overgrips but what are the lightest replacement grips. I head Babolat VS Excel is light but TW doesn't have it.

Which leather grip is the lightest?

THanks

Wilson Cushion-Air is pretty light I think.
