A long session of TB searches finally led me to this thread, which is touching on nearly all the questions I have right now regarding my own stage sound, so I beg your forgiveness for bumping such an old thread!
Background:
I started doubling (60% UB, 40% BG) in a folk-rock/alt-country band earlier this year. In the past I've used my Chinese carved UB through a Genz-Benz Shuttle 9.0 into a Audiokinesis TC112 v1 (4 ohm) to great effect. Love the wide, open tone for upright at low-medium volumes. However, with this current band I just can't compete with the stage volume when on the upright. I run into feedback problems and find myself pushing the amp into overdrive, and eq-ing for crappy tone just to get the volume I need to hear myself.
This summer has been busy for us and I've played a number of shows where backline has been supplied, often including a 410 cab. What a difference it makes being able to move that much air! This last sunday I was supplied with an ampeg 410 which I ran with my Shuttle 9.0. It sounded great, and I got more volume with my amp turned down lower and was able to dial in a better tone on the Tonebone PZ-Pre I've been running the upright through.
My thinking at this point is that I need to have the option to move more air on stage, and a 410 will get me there. I've been reading up on the latest and greatest 410s of the day but haven't seen much about how they fair with upright. To be honest, I'm not too worried about getting the perfect tone out of the stage rig because FOH is going to be what people hear anyway. Down the line I plan to send separate DIs to the board for each instrument, and really just use the stage rig as monitoring (I too have suffered from ass-sounding monitors when the stage rig wasn't enough

).
TL/DR:
I'm looking for a cab that sounds good with UB, doesn't weigh a ton, and hopefully isn't too pricy, that I can use as my stage rig for loud gigs. To the OP, what did you end up getting for your run with the CCDs? I bow to the wisdom of the Jedi Council.
