WI hubs comes in GOLD color and are good mechanically. I'd say its worth it!
I have DT240 with the 36t upgrade and also steel freehub upgrade. Its a good hub.
The best part about it is that it takes about 3 seconds to dismantle it for cleaning and lubing. Tool free!
Dont even need to remove the cassette. another good thing is that almost all bike shops in the civilized world can get parts for it quickly, especially in europe.
They are also tried and proven very reliable over the years. And if you ever manage to break (like split one in half) one they usually send you a new one.
Those are the 3 best reasons to get a DT hub. DT350 is the made in taiwan version, i have those too. good enough. DTs dont come in GOLD though....
Being able to get spares (quickly) down the road in 10 years or so is important to me. But WI has been around since at least 95 or so, so no problem there really. But they are not as widespread as DTs.
