I'm looking to get some pads for my Flex rotary and I'm a rotary noob so I need some advice from you guys. Since Flex says this polisher works best with 7" pads that's what I'm going to go with. Unless there are some pads I've missed, that leaves with a choice between Meguiar's 7" Soft Buff pads and the Lake Country 7" Kompressor pads. What are your opinions of those pads? Which do you recommend?
