Nice axe. Whale blue is a very variable color, and that one's very pretty indeed. My only blue PRS is CE22 in Royal Blue. Some of the PRS greens can be a little odd, but the Emerald really speaks to me and I wouldn't mind having one eventually. I mostly buy guitars for feel rather than color, but core PRSs nearly always feel good to me.
I have two McCartys, one korina/Brazilian and another with 57/08s. Each one great in its own way. The 57/08s are among my very favorite humbuckers; they have this cool 3D thing happening and a vintage sepiatone vibe that just makes you want to drink whisky and play the blues all night. But the korina is super lively, beautiful (Vintage Cherry) and really amazing sounding in its own right. I agree korina has a certain agressiveness that gets rude when you push it- quite different from the smoother, more sophisticated character of mahog/maple. I love the feel and sound of korina guitars; have a bunch of 'em but only one is a PRS.
