I have owned 2 sets of Open pro, both 32 hole with Shimano hubs. One set, which I still have, is actually the early version of Open Pro, Reflex SUP rims, even narrower, with Ultegra 600 hubs. I bought both used, so I do not know total mileage, but I have put thousands of miles on them with only basic truing needed. The 600 hubs probably need maintenance as the front has a bit of a click to it. The only drawback, maybe, is the width, but really not an issue. I have had up to 38mm, actual width, mounted on them with no issues. So; rims a nice ride, durability and low maintenance, and great price. What's not to like? As stated above, the frame set is likely to be the limiting factor for tires.
