I think the Mustang IV would be a better choice... 2x12 and plenty loud to get where you need to go... I'm all about overkill when it comes to amplification, though.

You may want to consider a Fender Deluxe Reverb Reissue... Classic Fender cleans, loud enough to gig with, classic cleans, sounds great when pushed, classic cleans, and did I mention classic Fender clean tones? Something to put on the list for sure.
