Winegasman,
I used to clean records much the same way as you are now. I do think an RCM makes a huge difference with cleaning. You don't need to spend a lot of money on an RCM. I built one using an old Hoover vacuum motor, a lazy susan bracket and some plywood. About $50 and you could do it for less.
I use RRL always and I also use AIVS on the really dirty ones followed by RRL. If you're not using a vacuum RCM I don't think I would bother using either product because you're not getting everything off of the vinyl anyway.
