I'm sorry, I'm sorry, Tim! 
I emailed Proper Auto Care about the 6" counterweight. Maybe if, after I start using the 7424 after a while, and I feel like it would be handy, I'll get it. Otherwise, you made a point of how it's not as essential right now.
Question- are the Meguiar's pads all flat? The ones on PAC were said to be concave. Which is better? The concave ones, I read, said they helped prevent splattering, errr.... ?
