As said, Rob, having no alternative to the BT012SS available in Europe makes the choice easy...

I am all around very happy with the BT012SS, have used them in SPA down to an angle the alternator cover of my series 2 Jota scratched the ground, so can not claim in any way about them. However, for a touring bike like the 1000SFC, I would expect a bit more durability.
Romeo: 8.000Km - I have to check what I do wrong... my rear is worn out after roughly 3.500 km latest. Had even a high speed run from Bavaria to Cologne (630Km or so) and had to bin the tires afterwards (they were new when I started my Trip, which was roughly 1.200km long...

). Seams they don't like high speed on the straights...
