Check out this rig by Steve K
As we all get older, we tend to find easier ways to lighten the load and reduce setup/load out time. There have been several threads here about that, but I applaud any ideas to make it easier. I just found out today that I have a torn meniscus in my left knee, and no doubt came from equipment moves. So, I will not be jumping off the top of my piano tonight. 
I no longer use a heavy amp, and the key controllers are lighter, and wheels have become my friend. I am also seeing a trend by venues in shorter load in/out times, and smaller stage area, which furthers the need for compact rigs. Thank goodness technology has moved so quickly to benefit us all.
But, of course, this technology is wasted on many sound guys. Ahh…the smell of clothing drenched in cannabis smoke, and breath of stale beer and cigarettes. They remain unchanged from day 1…including underwear…if worn.
