Which one of these rims will work with Badlands?

Ok, im pretty much settled on what tires i'm upgrading to on my Savage Flux. But im really confused from these rims from JConcepts. What exactly is the difference between the "Half ups" 3310 model and the "non" Half ups 3308 model?

I need whichever to work with my Proline Badlands for 17mm hubs

Any clarification would be great so I can get these ordered on Monday at my LHS.
