I have LS, too, and I think it's easy. Chrome goes well with LS like Lowenhart BS5s, but they're too impracical (cast 20s, very heavy, overpriced). Volk GTCs in gunmetal, TE37s in black, and SF Challenge (gold, black, or gunmetal) all look good.
For the two choices you gave, I'll say the Supermesh because they resemeble the BBS LMs, which is one of my favorite sets of wheels.
