Hi,
I'm now more of a bike tourer than a randonneur at this point, and, while those Hunt carbon wheels look like fun, I would never use a wheel with only 24 spokes for loaded touring. Not sure I'd use carbon rims, either, but's that's debatable in some circles.
I've had very good luck with Velocity wheels. I've used their Cliffhangers with 36 spoke rims for the Great Divide MBR, and that was probably overkill. I think the Dyad with 32 spoke rims would be my choice for a durable wheel for most touring conditions. If you're going to do an around the world adventure on a fully loaded bike then the Atlas would be the best choice. They're American made, and the customer service is excellent. I wanted some 26 in Cliffhangers in silver for a vintage 26" MTB (so I could safely run tubeless tires), and I called and spoke to them. They assured me they'd have them made soon, and took payment over the phone. They were delivered in 3 weeks in very perfect condition - nice, protective packaging. They've been great. I also have several bikes with A23s, which would be fine for gravel and credit card touring. Please use 32 spoke rims if you plan to tour loaded.
Good luck!
