I can suggest the Dimarzio Injector neck for the HSH combo, which i tried on my silo. It is single soil sound-ish and has enough output to balance with the humbuckers. In opposite to the blade made chopper, it sounds fantastic when splitted! Really awesome pup for HSH and HSS Axes. I heard the rumor, that the early Luke III HSS has injector neck's for middle and neck position.
