I just ordered and received a Holydiver and a Trilogy Suite for the middle and neck positions of my HSS strat. But unfortunately I haven't had a chance to install them yet. From all I've read, the Holydiver would likely get the sounds and feel you're after. Consider a Trilogy Suite for the middle singlecoil position, and then a VHII for the neck humbucker as Telerocker suggested.
The Holy Diver (calibrated set) with the Trilogy Suite in the middle has been my setup for many years "Great Combination" I also use a Schaller Mega-E 5-Way switch that can config the coils in different positions rather than the traditional bridge to neck.
