I can't talk about the specific rims you mention, but in my experience, rim width hardly makes any difference at all. I weigh about 240, so i favor wide tires. On several sets of rims over at least 20 years, I've run tires from 23 to 41mm without any problems related to width. The wider TIRES make a big difference, but I can barely feel the difference between narrow and wide rims. Initially I worried that the big tires might squeegee around on the narrow rims, but with reasonable pressures (only around 65-70psi with 37mm Paselas), they're stable and secure.
I do nearly all my riding now on 35mm tires on my "fast" bike and 37s on my tourer. Sometimes I put 27mm Roly Polys on the first bike, but to me, the big sacrifice in comfort isn't worth a relatively tiny increase in speed (full disclosure: I'm 65. Your priorities may be different).
