I can't answer your question directly as none of my Strats are built to have a Strat sound. However, one of them has a Seymour Vintage Rails in the middle slot and it sounds pretty Stratty to me in that slot.
The reason for my posting is this: are you sure you want your Floyd non-recessed. If so, remember that you have to have an angled neck pocket and the neck angle will be more like a Les Paul than a Strat. Also, one good pull-up on the Floyd if not recessed may damage the finish under the locking bolts.
Nothing wrong with non-recessed, just food for thought.
