Fastest Rom?

[Icedgreece]

I'm sure this has been asked, but not recently. I am looking for a fast ROM, that has no keyboard lag, youtube, and when the phone slides in or out, there is no lag.

I am tired of all this lag on every ****ing Rom I have used. I am sick of this phone, but I need another month until the contract is a year over.

So, what is the fastest Rom out there? WM 6.1 or 6.5 if fine !

Thanks,
