We've got Sun Rhyno Lites, laced to a generic 20mm thru-axle hub up front, and XT rear. No fancy double butted spokes for us - just straight gauge 14g stainless, painted black. We had custom titanium 203mm discs, but they were crap. Great heat dissipation, but really short life. Now we have Shimano XT 203mm discs front and rear. We're using Avid mechanicals, as the bike is coupled, and was supposed to be for touring. I've got a set of Magura hydros, just need to order some braided lines. Other than the ti discs, we've had no problems whatsoever.
