I think the old lie angles were all based on basic geometry which would give you lower needed lies. I think they now understand how the club act during the swing and the lies have moved accordingly.
I don't recall the SW on the old stuff. The clubs were heavy overall but they were shorter so the swing weights were probably in the high C range. Ping for years, was always lighter in SW than the other major brands.
I did get my T200 irons in the spring of 2020. The models shown in the photos are significantly different in appearance from mine. To be honest, the original models look a little busy, I like the sleeker look on the new T200. But looks aren't really the important thing, its how they work for you. Mine work reasonably well.
