I'm working on a new endurnace bike build and I'm looking for an endurance wheelset that can handle a bit of everything and is wide to run up to 35mm tires. I really like the look of the campagnolo shamal carbon c21 wheels, the price tag is not terrible for being campagnolo but wondering if there's anything out there that might be a better value and has a similar spoke pattern

pertual

  those are twice the price of the campagnolos, but they do look pretty sweet

If people know their stuff about wheels, this particular 2:1 lacing pattern Campagnolo called "G3" requires high quality rim that is very stiff, otherwise the spoke could break easily (or the nipples depending on the tension).

If you are looking for this pattern in a cheap Chinese wheelset, my answer is don't risk it.
