Downsizing is good, combos are good, or can be, and anything that reduces the number of things to be carried and plugged in is good. All this lowers gig stress in my experience. A combo that is easy to carry lowers it more if you need to be on and off stage quickly and out. But the list of light, portable combos that sound good and produce the required amount of, er... 'heft' is short. They are all expensive.
