I had a feeling you'd go this route (or wanted to in your heart!).
Funnily enough, I have ITs, Apaches, and Sultans.
I would say that Sultans are the "softer" of the three sets. More polite and refined. If I want to play Mark Knopfler, Sultans of Swing, I feel a lot happier on Apaches. All three will do it, but Apaches just feels right to me.
I would also say that Apaches, in my experience, will travel more into IT territory than IT's will into Apache territory. The Apaches seem more versatile to me - and they've got plenty of honk when you need it (I bought them expecting to have to get used to weedier/thinner - no way, they are pretty ballsy).
BUT - when playing, I feel happiest and most at home on ITs. I have a feeling you might as well.
One last thing, though, I've never put ITs with a maple board - when I got them into my Roadworn 60s it was a match made in heaven, so they've never been moved. I've not even touched the height screws since I first set it up (in case I lose the mojo!!). But I've heard some don't like ITs with maple - too bright apparently. Not sure myself, in my experience, how that can be, because I find ITs don't have loads of brightness. But others were fine with ITs and maple. My Apaches have been with both, works real nice with either.
