GK1001RB & GK MB500 (BACKUP)
After trying just about everything I settled on this head. Had one in UK and now have one in Canada. It's powerful enough for pretty much anything, and cuts through great. Only downside is you need a 3U case because the fan is mounted on top.
Bergantino HDN410 & BFM Jack12 (x2)
The Berg is super sensitive, goes plenty deep enough and has a sweet high end. Plus has staggered speaker arrangement which makes a little taller. Still only 55 pounds in weight. The BFM's are custom made from Bill's design and are crazy good. Each cab is 12" 400w and have an Eminence BGH25 horn. With a slight pronounced mid, they punch through no problem and are very sensitive too. I have done an outdoors gig with no PA support. I only use them now when I need a small footprint.
