Given that I started this thread, it's only courteous to come back and inform everyone who has given me advice that I do now finally have some equipment on order. Without the advice I received here, it would have taken much longer to reach a decision and, with so many details to consider, I'm confident that any decision I might have made on my own would not have been so well informed.
In the end, I decided that top quality, low profile, simplicity and maximum reliability were the most important things to me. This ultimately led me to reject the Schoeps MK capsules->active cables->pre-amp solutions in favour of the more expensive and less flexible CCM mics with built-in amplifier. After careful consideration, I now have a factory-matched pair of CCM 41V mics on order.
I'll be ordering a Tascam DR-100 MK II in the next week or so to be my new recorder for these mics, but I also want to be able to use them with my old R-09HR if that necessity presents itself, so to that end, I've also ordered a P12 Tinybox from Naiant. I've written many times here that I didn't want to have to purchase and rely on custom-made boutique equipment that I'd have to import from the US, but because it's only an optional item here, merely enabling the use of a back-up equipment chain, I can justify a Tinybox to myself on those terms.
I've yet to figure out exactly how Ill stealth with them, but I'll work something out.
All being well, the first results with this new rig should start showing up some time in June.
Thank you to everyone who helped me along the way. A special mention must go to Acidjack for coaching me through the whole decision making process and really caring that I made the right choice.
