Thanks all - loads to look at - the Corsair K63 vs the Logitech G613 looks like the battle of the most mainstream manufacturers of wireless equivalents of my Strafe - and the backlighting of the Corsair means that's in the lead (even though I'd prefer RGB, just so I can make it faint pure white by default, and colour-coded for games).
That said, neither are particularly minimal so the Anne Pro looks interesting, and it's opened a world of options now that I've googled suppliers, and seen what else they offer.
I really like the Microsoft - and that's a contender - just wish there was a black, metal-bodied, backlit option.
