We at one time used LG 3950 as our everyday vinyl years ago. It was polymeric and held up well. We were getting it from Trim USA there in NC. They stopped stocking it for 2911 monomeric I think. Our Trim rep. last time here was talking up the cast as being very good. Haven't tried it, but it's tempting. We still use LG Xign and 3880 often.
