I'm not gigging with anything less than a 2x12, 1x15 and 1x12 or a 4x10. It has to have massive overhead at any gig. If a "micro rig" can do that, then fine but I've never seen one that could. Even my 2, 1x12 Aguilars barely had enough beef. I'm skeptical about any of that low weight stuff. It seems to be only endorsed by guys who are fed up physically or can't handle the rigors of gigging properly anymore.
