This rig gives me 500 watts pushing into 12 x 5" Neo Power speakers. The PB-300 weighs 36 pounds and I can actually lift it with one finger. Carrying it anywhere with one finger is a different matter however.
Additionally, I can use the PB-300 by itself with my Bass Pod XT Live as the front end or the Super Flightcase by itself with or without the Bass Pod. I'm thinking it's going to be quite versatile actually. Or maybe I should say "hoping".
Check out this YouTube video for an idea of the size of the stack. Sorry about the fact that the demo guy is Japanese and most of us, including me, can't understand what he's saying. I do enjoy his pronunciation of the amp name tho.
