There was such a huge paradigm shift in both the way that racquet companies work, and consequently how pros’ racquets were prepared or sourced, starting around 1993 or so. At the crux of it was a shift to Asian OEM contracting by all manufacturers (with Head delaying somewhat, but ultimately shutting down tennis production at its HQ in Austria, and Yonex remaining the only holdout that I know of, still producing part of its line in Japan). Coincident to this came a change to a marketing-driven business model, as opposed to an engineering- or R&D-driven model, in a desperate battle for survival in a dwindling marketplace.
At the same time, upticks in the aerospace industry’s use of higher-quality carbon fiber stocks made them too expensive for tennis use, where “good enough” in a flashy new coat of paint with made-up “tech” became the new normal.
So in this new environment, with annual updates on inferior products marketed to the hilt, you are not going to have “iconic” models in the marketplace. You might have, at best, lineages of well-regarded higher-performance product (i.e., the Pure Drives), which were tinkered with almost annually and have custom facsimiles used by touring pros.
