I have the same 1 box vs 2 box issue (V2 and AD2k) but I love my V2, I couldn't ever give it up.
Since I don't stealth, I've never worried too much about 1 box, 2 boxes, 3, boxes, or more. It's always been about the sound. At this very moment, it's a 3 box solution for me (mixer, A/D, DAT), but since I run 4 mics I have always been pretty much stuck with at least a three box solution.
I've found the AD2K+ fits nicely in the upper pouch of the DA-P1 portabrace bag, so it really isn't any harder to carry it around. The biggest thing is the cabling. I tear everything down, so it takes me a few extra minutes when I setup to get everything cabled and setup.
