I'm gonna throw a curve ball here... umm... Apaches(!)
Watching the thread, I've been thinking "probably Slowhands", but I don't actually own them.
I do own Irish Tours, Sultans, and Apaches. If you're considering Irish Tours, then I would suggest that Apaches might be good, or possibly even better, for you.
I do blues/rock type stuff, and my main go-to strat is the one loaded with Irish Tours (a Roadworn 60s with rosewood board). That gives me a hard-edged strat tone - pretty much the "stock Andrew tone" that I was seeking for years.
I was expecting Apaches to be polite, possibly slightly thin/bright, but I wanted a set anyway. I was amazed when I got them. I have them in a Roadworn 50s with maple neck. I find them more versatile than the ITs, capable of feeling fatter and, actually, more aggressive... If I was buying again and could only have one set, I would get Apaches.
ITs seem to have this hard-edged upper-mids thing going (that's what I hear anyway), Apaches seem to push across a wider spectrum and therefore feel fatter and more "robust" to me. They both rock pretty much the same amount through the same amp settings on my kit, I use the ITs when I want harder, more biting, Apaches when I want fatter, more punch.
My gut feeling is that it might actually be a toss-up between Slowhands and Apaches for you... I'll be interested to hear what the BKP guys say.
And I very much agree with gwEm - make sure you have a tone control on the bridge pickup, if you haven't already. For me that's half the battle in guaranteeing you'll use a strat bridge pickup for more than just stripping the enamel off people's teeth!
