3" backing plate on 6" GG unit

[GLS0628]

I am a weekend warrior looking for a better/easier way to take care of 3 or 4 everyday drivers. I am interested in the 6" GG. I am planning on ordering the a 5" backing plate (http://www.autopia-carcare.com/lake-country-pads.html) to be able to use the 5.5" pads. I am interested in knowing if instead of also buying the 3" machine wouldn't it be a little better to get a 3" backing plate (http://www.autopia-carcare.com/lake-country-pads.html) and the 3.5" pads from griots? I see no reason to buy 2 machines but instead just use the one unit and change backing plate (http://www.autopia-carcare.com/lake-country-pads.html) when I wanted smaller pads.
Also I am reading mostly that users prefer the Lake Country pads over the Griots. Anyone with an opinion? Since LC does not have a 3.5" should I go up to a 3.5" backing pad to use a LC 4" pad?

This is the start up items that I was considering.

6" GG
5" LC backing plate
5.5" LC CCS pads
3" LC backing plate
3.5" Griots pads


How about recommendations on light cutting compounds, polishes, and waxes?

Use the 3 inch backing plate for the 3.5 inch pads. That's what I do and works fine.

I just put the 3 inch backing plate on and run the unit on a lower speed number. Works good and not a had an issue. As you, i seen no reason to spend extra money on two DA's.
