Ah yes, the never ending experiments. Don't think you guys have cornered the market on experimenting, though, as we do it too!
Case in point - I take care of a couple of cars for a guy in Redondo Beach, a 2007 Mercedes SL55 AMG and a Superformance Cobra, both black. The Cobra loves M205 on a rotary with a W8207 polishing pad spinning at 1200 rpm - the finish is absolutely stunning and completely hologram free with that process on that car. The AMG absolutely hates that process though. In fact, it seems to hate the rotary in general as doing exactly the same process on it yields hologram city. It looks like it was just hit with an old wool pad and an old school compound. And the AMG is not a big fan of the DA Microfiber System either as it will noticeably haze the paint, in fact about as bad as I've seen with the system. But what that paint just loves is D300 on a W8207 foam polishing pad via DA at speed 5. Loves it. No haze, defects gone almost immediately, and the finish is beautiful in no time. And the craziest thing of all? It actually played quite well in direct sunlight on a pretty warm day. Who knew?
So experiment away - just don't expect every experiment to be a winner!!
