commute, no; twisties, yes
powers will wear quickly for super slab. If you are wanting a more commute friendly tire that will do well in the twisties, the pilot road 2s are now available. They are a dual compound and have a road center and something more like the powers on the edges for twisties.
mileage on them depends on how hard you work em 4k-5k is about average.
