Is there such a beast?
Is there such a beast as a single 200W FLEXIBLE solar panel? A few days ago, I saw one for several minutes on ebay, went searching elsewhere, went back to ebay and it was gone, never to be seen ag...

It's not common having MPPT with 2*100W. Important numbers with MPPT would be Imp (not Isc), and Voc.
With MPPT you can wire in series too. In this case, the panel with lower Imp will force the other panel into same Imp, this will drag the total wattage down - a little. Not too important, you can still wire these particular panels in series as long as total Voc is within the controller input limit.
Series wiring is much easier than parallel. You just use MC4 #10 cable all the way to controller.
One drawback of series is that higher voltage results in lower MPPT efficiency, but with voltages as low as in your case, I wouldn't worry.
I can't agree about exceeding the Voc input limit of controller. You can exceed MPPT current rating, yes, - TAD. But I don't remember any MPPT of "RV size" that could digest excessive Voc with no ill consequences.
