Did exactly that earlier this year. Replaced old FlowEX’s with the 30mm DT XM481’s on a set of DT 240s hubs with Sapim D-Light spokes.
The DT rims built up much easier than the Stan’s did which I take as a good sign. Over the life of the Flow’s I had the back wheel lose tension once and go out of true 2-3 times (not drastic and easily fixed).
By comparison the DT’s haven’t been touched since I built them, they were the easiest wheels I’ve ever built and ended up being the straightest. Even taking into account the squorx nipples and the PHR washers, they went together faster and easier than anything else I’ve built in the 20 odd years I’ve been building wheels.
In short (too late I know), Im a big fan of the DT rims, they seem much sturdier than the Stan’s which came off my wheels with several dents and dings and as I said went together beautifully.
#EDIT : One other thing I noticed, the Stan’s rims were heavily corroded around the spoke holes when I dismantled the wheels. That’s depite the bike living in the house and my lubing the nipples when I built the rim. A bit of corrosion I can accept but the rims were only a couple of years old and as I said, heavily corroded.
