Ummm.... Ya.....
I really haven't found a "go to" combo with my Flex 3401 either. Tried Megs, Optimum and LC Ultra MF pads and still get better results with my GG6 & PCXP. Nor sure the forced rotation matches my style of machine polishing.
I am finding that I don't like polishing with my Flex 3401 as mush as my PcXP. I can, and it finishes fine but I think the PcXp just does it a little better.
For me there the Flex 3401 excels is in cutting / compounding. The 3401 with LC PFW is great for faster cutting. Also I find the 3401 cuts better than a standard DA when using Yellow or Orange cutting pads.
