I am using at the present Mitas E-09 for front and rear on my XT600E done so far round 1000 miles - not bad tyre for a price (�102) delivered.
Good on dry
wet - well you have to be aware it is quite hard tyre and man-hole covers are no no (real experience

- nearly losted it)
off road oweral very good mud is not a issue
I would say decent tyre and should last more then TKC we shall wait and see.
Mitas E-07 only run at rear
off road great untill it got to a realy mudy
road good (wet i would say so so did not trust it so much)
hope it helps
Have fun
