Fran, I am happy with the weight and performance of the CM-30 when I use an 8 channel Yamaha 400 watt system with 4 15 cabinets. That's when I do a "level two" single.
My big rig is 2 1000 watt Crowns with appropriate cabinets, including 18" subs. For that, I use up to 4 2 x 10" Carvin wedge monitors and a separate 600 watt power amp for power.
I am actually planning to use the 330 with the CM 30 as a monitor for an outdoor gig at a gig coarse this week-end.
Sometimes, I just grab the easiest to reach stuff. Other times, I let my kid, who sets up the equipment for lots of my gigs, just choose what will work.
Lots of times, for my singles, the trio or bigger jobs, I just show up. The equipment is all up and running. I just sit down, play and bitch about what my "roadie" has selected.
Man it's cool getting old and obnoxious!
R.
