Just a little update on my end since I seem to be one of the few still purchasing SP pieces.
I want to give a particular mention of the Bi-Stretch R-Nylon pieces that came out this past FW season. It's essentially Schoeller Dryskin, except it feels...better? The handfeel is nearly identical (7% EL/93% PA vs. Schoeller's 9% EL/91% PA), yet it's slightly thicker and sturdier due to being less elastic.
Anyways, I ended up buying 2 pairs of the same wide-legged pant on sale (~$300/pair) and I wear them 5-6 days/week. Insane pair of trousers.
