Mavic CXP23 rim replaces CXP21?

I might not really suffer from OCP but I do like things to match. My Bianchi is equiped with black anodized Mavic CXP21 rims and the rear seems to be dented and might need to be replaced. The CXP21 is apparently no longer in production. One of my other bikes has CXP22's which are similar but not quite the same and I was leaning towards using one of those until I popped on the Mavic website the other day and found that they now make a CXP23 that to the naked eye looks exactly like a CXP21 right down to the decals. Does anyone know the difference between these? Is there any? I suspect the 23's are just updated 21's and would make the perfect replacement. I don't want mismatched rims and I don't have the bucks to replace both (although my bike has been asking for a new set of Vento's for Christmas I don't think my wife is gonna go for that). Thanks.

Yeah, CXP23 is the twice-updated version of the CXP21. Should look very similar, too, where that's concerned. I always pull the logo-stickers off of my rims before I build them, and if you do that no one will know the diff without really careful examination of front vs. rear rim.

I also need to replace a cracked OEM Mavic CXP21 rim on my wife's bike, 2003 Cannondale R600, CODA Expert hubs, +/- 3K miles. The CXP 21 does not have any eyelets which probably contributed to the cracking. I would like to do a straight swap using the original spokes. Are the CXP 22 or CXP 23 the the same or close enough cross section and profile to allow this swap?

I'd look up the effective rim diameter in a spoke calculator to be sure but based on eyeballing the rim depth (well, actually, holding my micrometer next to the rim sunce I didn't feel like taking the tires off) the depth of the CXP21 measured around 19mm, the CXP22 20mm and the CXP23 21mm so they are close but not the same. None of these have eyelets either. Also, the CXP22's have a sidewall wear indicator groove so they look a bit different from the other two.
