I've seen multiple reports of spoke hole cracks in newer Open Pro rims. They aren't as bombproof as they used to be.
For riders under 200 pounds, a 24 spoke front and a 28 rear would be fine. And some wheels are still strong with fewer spokes.

new wider rim designs that spread out the base of the tire. This allows more air volume, making a 23c tire act like a 25c, and a 25c like a 27c. It might help reduce pinch flats too. If I was buying new wheels, I'd look for wide rims.
Old rim widths were usually 19mm. New ones are 23mm and up to 25mm. Some new rims:
