If you want to stick with Michelin, then Pilot power 3's are great, longevity strictly depends on how you ride. If you ride in colder weather alot, <60 degrees, then look into a sport touring tire like the pilot roads. Pilot roads will grip better in the rain and colder weather than the powers and overall last longer.

 

 

I have been using the pilot road 4s and they are good tyres. Plenty of grip in the wet and very nice in the dry as well.
