If you like the single coils but feel you need a bit more power, you may want to think about a Sinner in the bridge instead of a humbucker. They don't sound like humbuckers (nor do they try to), but they do sound awsome. There are some nice clips in the Players forum that are worth listening to.
As for the middle and neck, if you like SRV, you'll love Irish Tours. They also match up nicely with a Sinner in the bridge.
