Ah geez these are tough choices. Seems I'll have to take a step back and see how much need I actually have for the high end frequencies. Although having these options to consider makes me feel spoiled as a musician, a good time to be shopping for new speakers it seems.
Well. With a good ear and EQ/sim you can tweak the 12" cabs to approximate the 10" cabs more easily than trying to go the other way. Being able to defeat the compression driver is easier than trying to create one that isn't there. If you're running much fuzz/distortion though, you'll likely not run the compression driver.
