Ah, I was going to suggest these. Not that I've used them, but the guy on the Metzeler stand at the Ace Overland Day suggested they were the best alternative for the Tourance, see pics at http://www.metzeler.com/site/uk/products/tyres-catalogue.html
The Tourance Next seems a poor choice.
I'm looking forward to the Enduro 1 and 2 to replace my TKC's when they wear out. (From the link above)
(As this was in the East Mids section not the 1200, I thought I'd throw in my two penn'oth.)
