I had those on my 700 this summer. They are good for garbage now, pretty much don't have any lugs left. They've been a good tire, they have amazing control when drifting. I'm not impressed by their forward traction though, it's pretty hard to wheelie with these unless you are on very tractable ground because they want to spin a lot.
The best thing about them is that they are both pretty resistant (6ply) and pretty light, so they are pretty nice overall.
I will be running something with a bit more forward grip next year...
