Appreciate all the great responses and insight. Im willing to put in the time and dedication to learn. I just feel so much more comfortable with a rotary then a da. Just the decision of getting the flex or a dewalt 849x. Im a pretty big guy (6"4 290) weight is not the issue just have hands like baseball mits. Lol
Used the DeWalts a zillion years ago and they are great... Big, though...
I like the Makita 9227C I have because while it is long, it is not very wide, and It works well for me in terms of balance, and power... And the longer body of the Makita might be easier to work with your giant-man-hands...

In my work, I will always pick a least aggressive compound over a more aggressive compound and work it a little longer and harder to get the results I want and then have a really nice clear finished product..
The Makita is really good for this kind of hard work and doesn't complain or have a fit when I sometimes put down a LOT of pressure on it..
Other times, with other paint and needs, just the 10lb weight of the Makita is all needed to get the correction, so I like that too..
The Flex PE14-250 is great, small, and light, but makes a lot more gear noise than I care for.. Handier because it smaller...
On all Rotaries I have, I have installed a standard sized spacer between the machine and Backing Plate to allow me to get the pad into spaces where the machine might be in the way, like under side mirrors, over side mirrors, around some areas of painted grills next to lights, etc... Basically anywhere you need to get closer and not have the machine head/body be in the way..
You will now need to remember to WATCH that spinning spacer and NOT let it contact anything !!!
Like I have always said, you totally need to be watching and watching everything that is going on while doing this at any speed... Cant get too distracted or thinking about that hot babe walking by....

Good luck !
