I had a Big Twin when I was still gigging, it was the best cab I've ever used bar none, and at 55 was a one handed lift into the estate. The wheels and top handle made it very easy to run around studios and venues too.
I went FR/modelling with it very early on, Line6 Bass Pod Pro XT rack and a big QSC power-amp, and the Big Twin just amplified whatever I sent to it, and amplified it to seismic levels without a twitch.
If I was to return to playing live, it would be with a Barefaced cab, and probably a Big Twin, can't recommend them highly enough.
