It depends on what you want to play in what guitar....
I could see a P-Rail totally working in the neck if what you want there is a P90 for Rawk rhythm and fat blues, a single for cutting Strat tones, and a Parallel HB for jazzier clean stuff.
But yeah - Any one HB guitar that I have that specifically NOT for Jazz, I'm going bridge, and in the case the 18k HB setting is a phasor set to KILL!!!!! So metal/hard rock totally in scope too.
