My rack (see post #12) weights maybe 40lbs. This includes everything I need to make noise (preamp + power amp + effects + presets), I store my midi controller in one of the lid, all the cables are connected inside ready to go, and everything is fully protected against damage and weather.
What's the weight of your head amp?
What's the weight of your pedalboard + the hard case to store it + all the cables?
I would thing it weights more than my 4u rack (which is stereo).
I also have a 2u rack with an Eleven Rack that I use for ampless direct to FOH (mainly for bass now). Weights less than a pedalboard and takes 2 minutes to setup (XLR cable to FOH, cable to power outlet, cable to guitar, and cable to midi controller. All already connected to Eleven Rack).
I have a small pedalboard that is battery powered and can slip in my gigbag, but I really don't understand the big pedalboard thing and the form factor associated (plus having to deal with all the patch cables, power supply, tap dancing, one sound per pedal, or getting on your knees to adjust between songs, inter-connect/dc cables getting loose or knob position changed during transport and dealing with 9v/12v/18v pedals).
