Detailed Image seems to be having a sale on Lake Country products but they only have the flat pads. Are CCS pads really that much better, or do flat pads have their advantages as well? I kinda feel like purchasing some pads now because of the sale since I will be purchasing my first polisher ever, a Flex XC 3401 VRG, pretty soon as well. Any pad experts, I need your advice and tips from your years of experience. Thanks.
