Wheelbuilding / Wheel Building / Wheel build help

I'm about to build some 650b wheels from my Kinesis Tripster AT so would like them to be able to take some abuse for my upcoming All Terrain adventures, as per the Kinesis promo video!!
I already have two 32 hole Stans ZTR Crest rims, I was hoping for some advice on the rest:

• Hubs...I'm leaning towards Hope Pro 4 as they get great reviews and come in 110mm front\ 142mm rear allowing for 12mm through axles. Is there any other glaringly obvious options I'm missing?
  
• Whilst on the topic of hubs is there a difference between a 110mm boost hub and a 110mm hub? My guess is they are the same, and the fact a hub is 110mm as opposed to 100mm is what makes it 'boost', but the DT Swiss website for example lists them separately!
  
• Are double butted spokes suitable for this build? Hoping to do some bikepacking with tent etc. if that makes any difference...
  TIA
