Bingo! I started with the PC7424XP and moved up to the Flex 3401. Love them both and still use the PC. I have my PC applying the sealant/wax and it's a 3" BP. The Flex is my Brute!...You went a similar route. But a good way to get good at detailing. The GG6 from what I hear is more powerful than the PC and you can't go wrong with that one either.
