Sounds like a good combo to me. As far as other ideas... There's lots of great stuff out there and what would be best is partly a matter of personal taste and partly a matter of budget. For whatever it's worth it's hard to go wrong with any WTB rim in my experience. Price to value ratio on their products seems really good to me. When it comes to hubs pretty much anything from DT, I9, Hope, Chris King, etc. is gonna be good. Any Wheelsmith, Sapim, or DT spoke will also be a good choice.. When it comes to nipples I'm a little fussy. I'm a big fan of Sapim Secure Lock nipples. The company I build for uses that nipple exclusively and I agree with their judgement. I like using them for multiple reasons that I don't want to get into here (too long of an explanation). About the only nipple I really recommend NOT using is DT Pro Lock Squorx. Again, the "why" is a little involved. If you really wanna know, hit me up and I'll tell you.
Have a great day!
