Hot Rails Neck with Custom Hybrid bridge?

[eclecticsynergy]

This is what I'm debating on if I go from active pickups to passive pickups in my Charvel Model 5FX which is a neck-through construction with a maple neck and poplar body. The Seymour Duncan 59/Custom Hybrid Trembucker in the bridge and a Cool Rails for the slant single coil position in the neck?

I think the Cool Rails is a very good neck choice. Far better for a dark-ish sounding guitar than a Hot Rails.
The Hybrid always sounds great at the bridge in S-types (except for the OP's, which must be exceptionally dark).
