Been bit by the mix scenario.
The lesser tyre on the back if you have to do it is the best way to go, but peeling into a corner in a spirited ride and having the front stick nicely and having the back let go aint a pleasant experience.
Down like a sack of shit, bitter personal experience.
I have mixed 'em up for track use but stick to matched sets for road. Only recently on the way to work I came banging into a fave largish roundabout and felt the front end twitch and saw the stain on the road just as the backend "lit up"
But it stayed nice and progressive and slid nicely until I straightened up on the exit, I know its supposition but if I'd had a lower spec tyre maybe things might have ended up differently.
Shiny side up is always good, and I like the insurance of the better rubber. [moto]
