my experiences relate to a XTR but hopefully wont be that different.

Tourances - ****e
E07's - very capable tyre so long as the off roading is pretty dry and firm. (used in snow)
E07 rear with TKC80 front - very good combination but the rear will struggle off road before you have major issues on the front.
E09 rear with TKC80 front - best all round combo I have tried so far.
