It is possible to use the 6.5 pads with the backing plate but I wouldn't suggest it. The problem is that you have no hang over. You will have the edge of the backing plate sitting right there ready to
scratch the heck out anything it touches. I have used it this way for a finishing pad but was nervous. Just get a smaller backing plate and use the smaller pads. A begginner will have a much easier time learning with the smaller pads.
I like the Meg's soft buff pads and the smaller
Sonus pads over the LC pads. The only reason being that the dLC orange is a very stiff pad and difficult to use with the rotary. If you are jsut starting out with a rotary, the softer the pad the easier it will be to control.
I too own a couple of the Makita's and love them.
I was in AutoZone the other day and saw that they have rotaries for 59 dollars. Has anyone ever tried one.
