Other than cost, there's no advantage here over a Phil hub laced to an OC rim. An allen wrench gets the cassette (okay, the entire freehub) off to access drive side spokes and the OC rim allows for near-equal drive/non-drive spoke tensions. I'll pay the extra $350 for the proven Phil. Over the life of the hub, 250,000 miles for my last one, the cost difference rather disappears over time.
Even though I do a lot of off-road touring, I've never broken a spoke on a rear wheel. It's not like I baby them; I've broken axles, destroyed tires and, in the freewheel era, just devastated freewheel bodies. (I'm not light, weighing in at just a few kg short of clyde.) In my experience, a well-built wheel just doesn't have spoke breakage issues.
