Jamie has my Navis at the moment.
In his opinion they are a nice looking and more importantly a very 'true' wheel that seems to be built pretty well.
Ok, so some might not be happy with the paint finish, but I've been unhappy with the paint finish on expensive alloys before. It's not the end of the world to have them powder coated, which will often be much better than a mass produced factory finish, plus the obvious benefits of choosing your own colour and making them a little more customised. Remember that although Duchys wheels are exceptional quality, the Navis are officially load rated and in bigger sizes, which will appeal more to the purists that mod on the legal side. In my opinion, you cannot really compare his wheels with a factory produced wheel, they are two different types, albeit both steel.
