My stock wheel on my bike was squeaking and creaking. I brought it in several times only to hear that it was fine. I could not take the noise as it drove me crazy. I transfered that wheel to my daughters bike and it is silent. The mechanic was right when he said it was probably my weight 185 lb
I bought a hand build from the mechanic is a master wheel builder. He asked what I wanted weight or strength. I said I was not too worried about weight but did not want too heavy and would prefer it was stronger than lighter. I left it up to him
He laced a cpx33 to an Ultegra. It is a good wheel straight and true with no worries.
While I do not know the rim you speak of I am surprised you are having problems with the cpx 33. I am not easy on equipment and have no issues with that rim
