I've been using my UL112 for a good while now, and it is one of my favorite little cabs. It can get very loud and maintain a great punchy tone without breaking up.
I have a UL112 also, and the pairing between LMII and 112 is a very good one as well.
From my comparisons thus far, my best micro rig in order would be:
1) Schro Mini 10+ Light
2) Berg HT112
3) Epi UL112
As I mentioned the Schro is so small, light, punchy, and loud that it's a hard rig to beat. It also passes the wifes "cute" test, which in my house can go a long way. She didn't think the sound was all too cute which gives you an idea of how loud it is. This option seriously allows me to pack the LMII into a gigbag, sling the bass over one shoulder, and hold the cab easily in my other hand without much effort at all.
The Berg sounds very good. Not quite as easy to carry, but the added lows and highs of the LMII sort of completes the Bergs mid focus and makes this a very full and musical pairing. Not as punchy as the Schro, but it is more smooth.
Lastly, the UL112 and LMII. Sort of an in between the Schro and Berg. Not as full sounding as Berg, but easier to carry. Not quite as punchy as the Schro, but very close. It truly is in between the two cabs. It's lighter than than the Berg, but almost as awkward to carry.
Like I said, because I was looking for a really easy rig to carry, the Schro and LMII wins it for me, but I'm fortunate to be able to have all three at my disposal depending on the situation.
