...With pedals it depends if you are fan of Eggbeater,
If you're looking for Eggbeater cranks and wanna go with the 11s, check out Crank Brothers' trade-in program. They offer any of their "normal" pedals for $60 with trade-in of any old pedals, but you can also get the Eggbeater 11s through trade-in for $250. That's quite a bit better than the normal $450, even if it is still pretty shocking for a set of pedals. You have to call them directly to do that, though. (this is all assuming they are still doing the trade-in program)
Edit: If you have loads of cash you can go Clavivula with crank
Short of that, I've been really impressed with the Race Face Next SL's so far. Saved almost a pound over XTs on my wife's bike. Only notable downside is the tooth profile of the spiderless narrow-wide chainring isn't as agressive as Wolf Tooth and so we had some chain dropping issues. Looks like that was due to a Shadow Plus derailleur that needed maintenance, but still, I'll be very happy when Wolf Tooth releases their spiderless rings for the Race Face Cinch standard. They just had a teaser image on their Facebook page for it as well.
