The best tire I ever tested on 600 cc and 1000 cc is Pirelly Supercorsa Diablo III, dual compound so they last ok and excellent grip, most of the race bikes use these when slicks are not allowed or wet (in the country I live). But from seeing your typical riding I would not go for them, as they as supersport tires and you risk having poor grip due to insufficient heat input on them. The stock Dunlop's are plenty good for what you do, stay with them. Or go for any other sport touring tires, as they grip better than supersports when you ride them as you do, and they last longer.
