fender strat custom shop

What Fender pickups work best for a nice bluesy sound?
I have been looking for a long time for which custom shop pick ups i should put in my Mexican standard strat im trying to make it the best bluesy guitar i can possibly make out of it tell me in as much detail as possible what your opinion is. keep in mind i am really looking for a stevie ray Vaughnish sound.
Put Seymour Duncans at the neck for a warm, mellow bluesy sound. Vintage hot stack really sound good as well as the Hot Rails which has the fat sound of Humbuckers.
Both are good pickups for blues althouth the Hot Rails have a better output.
