So now I see you guys like to use 6.5 inches...ahem, for buffing, guys, for buffing (

), so now could you guys share your preferences on type and brand? I ask cuz I haven't seen any 6.5" pad other that Megs and foamed wool pads. I'd rather not use the Megs as they're pricey. I want a pad that is easily centerable too. Thanks a million.
