Contrast is pretty alright for fast and effortless power weapons. Talassar blue in particular works like the old Girlyman glaze and I heard BA red over metallics was also pretty good, haven't tried it myself though.
Blood Angels Red over Leadbelcher looks wicked. I tried it on a Deathwatch storm shield and it turned out great. It'd also be good for HH Thousand Sons.
