Hey Rzims, watch that White Inductries ENO stuff. It's well engineered, but the raw polished surface can be a real problem long term in the wet. I had some of the WI cranks. The surface of the alloy blistered, causing cracks. Raw polished (non-anodised) alloy on a mountain bike has got to be bad idea - unless you live in Arizona, or somewhere else where it never rains. I also have a White Industries ENO freewheel. That seizes solid after wet rides, and has to be freed off with machine oil. I guess the guys at WI never ride in the rain. In England we almost never ride without rain!
I like skinny '14/17G' butted spokes, such as DT Revolution or Sapim Lazer, which are 2.0/1.5/2.0mm diameter. Normal '14/16G' spokes are 1.8mm in the middle. Revolutions and Lazers look funky and save a bit of weight. The additional expense is negligible if having a really good set of wheels built.
I've settled on Mavic rims. Good quality, wide range for different applications, no availability problems. FRM hubs work for me. They're super light and well sealed - with almost no bearing drag. Mine are the older ones that use a genuine Shimano freehub body unit, so there are no spares availability problems. Try getting a freehub or spares for some of the current OEM hubs (usually made by Joytech in Taiwan), it's not easy.
