Well, I realize I am probably in the minority here, but 12s are my 3rd choice for guitar speakers; were I to find myself in your position, I'd go with the 2X10 - on top of a 1X15. Gives 3 possible set-ups, all of them great. And, given what we know of your skillz, I imagine you could whip the cabs during an afternoon nap.
But remember, this is a guitar rig - and that means reverb!!
Now, granted, I haven't heard anywhere near every reverb pedal that's out there, but of the ones I have heard, none sound as good as a proper spring reverb (for anything else, the engineer in me wants an actual chamber or a plate reverb, but for gitfiddle, it gots to be spring!)
Just a quick, highlights-only glance at Google shows stand-alone spring units ranging from $1900 down to $50.
But if I may circle back to David's post, when my youngest moved to Alaska, he left his Blues Jr. here for several years (until one of his friends was driving up there), and I had no problem with its reverb (far better than the one in the Silvertone 1484 Twin Twelve he sent back with his bud so I wouldn't be ampless - which is pretty acceptable with the general character of that amp).
And, if your problem with the Princetons was getting your preferred tone at in-the-house volumes, know that the Blues Jr. starts to break up sooner than any other Fender I've ever heard - which for me was a downside, but it sounds like it would be a plus for you.
But, as you have the heart of the rig ready to go, feel free to ignore the previous 2 paragraphs of my rambling. But remember, 10s & 15s, spring reverb.
