Thank you guys for all your comments. It certainly help and gave me ideas. First, I'd like to try doing the adjustment first if I can.

BB,
Are you able to point me where I can find Deejay's video ? I want to try doing the back-lapping as well but not sure where to get the grinding paste.
Is there a particular brand I should be looking for ?
Is there also a video on how to do back-lapping process ?

Thanks
