I upgraded my Soul Superfly's to the nano driver. Defiantly worth doing and remember you get 200 dollars back when you send back the old driver's.
Also agree that the upgrade is easy to do. They even have a video demonstration available on the Zu website now. If you can handle a screwdriver and follow simple instructions there shouldn't be any issues.
