Ok, after more experimenting with M205 and FPII, I found the following:
Using either a PC or Flex with M205, I am not able to achieve the same high gloss finish on medium/soft paint that I can easily get using a rotary. In every case, hazing and micromarring was visible in the right light. My LED Surefire did a good job of showing this, while 1500W of halogen didn't. The closest I got to a perfect finish was using a PC with moderate pressure and medium speed. Using a Flex, I could get decent results if I dropped all the way to Speed 1 for the last two passes. All of these were with Black CCS style pads.
Using either a PC or Flex with FPII, I can get a seemingly perfect finish with FPII. This was rather forgiving and gave nice results from Speed 1-4 and from zero to moderate pressure. To me, FPII is the much easier jeweling polish with the Flex. Obviously it doesn't offer the cut of M205, but that's not the point.
I tried UF and while it never gave visible micro-marring and a haze-free finish, the reflections were not crisp. I have a hard time putting words to it, but it's almost like it left something on the paint that wasn't removed with multiple alcohol wipes. I know people love this polish, and I've gotten decent results using it, its just not on par with FPII in my tests.
