What works well for most does not work well for everyone but that is part of the joy in cycling is we have so many options we can really customize our bikes to suit our own needs.

I have seen commuters destroy even rhynolites so there are some pretty abusive commuters out there. By destroy I am not talking about spoke issues but bad dents/flat spots, while not every type of damage is always preventable, sometimes having an overbuilt rim can be just enough to keep your rim from being damaged from running through a deep pothole one morning.

I am not trying to argue with you over if an A23 can handle commuting duty as it absolutely can, and is what I use personally. I am just saying that in my experience most commuters I have worked with could never tell the weight difference between the two rims and seem to appreciate the extra bit of insurance that comes from a tougher rim on their commuter as most of the commuters around here seem to have their bikes take a serious beating while locked up in racks with a questionable design. A little extra material is also nice when it comes to things like brake track wear as well.
