I have a NY151 (which I thought sounded better than the Traveler version) and a LMIII. That's easily enough for the bands I play in. If your band is much louder you might need a second cab or PA support.
Not to hijack this thread, but I was considering getting the CMD121P and a New York 12" to complete the rig. Is the general consensus that 2 single 12 cabinets aren't going to be loud enough to compete with most bands? Should I pair the 121 with a 102HF instead?
I never thought 500 watts into 2 12" cabs wouldn't be enough.
