I've not tried the dunlops, but have tried:
Road bias tyres-
Siracs
Battlewings
Scorpion Trail
Of which I thought the Pirellis were best

Off road bias-
TKC80
Mitas e07
Mitas e09
Karoo
The e09s seem to offer the best life/grip blend but squared off badly at the end. The Karoos are doing well. The e07s were the worst tyre I have ever used and I pulled them off before they were half worn.
None of the tyres have got above 5000 miles before being shot. I am a reasonably swift road rider.
