Great post Dave, and some excellent points.

I've been in many similar situations, and luckily, over the past 10 years or so, my own setup has remained very compact and pretty easy to set up/breakdown. And, it's always been the case of following the old Boy Scout's motto, "Be Prepared!"

I'm considering doing a duo sometime next spring, with a guitarist vocalist, using double Bose L1's (with subs)-in stereo...of course, I'll be using the Tyros4, which is as small as I'd like to keep my keyboard setup.

Again, lightness and portability are paramount, and stage footprint to be kept at a minimum...using the Bose means not needing monitors (I have my two Yamaha MS-60S if ever needed) and I have had previous experience using the same setup so I know it's great capabilities and very few, if any, drawbacks. Keyboard EQ is extremely important with the Bose system, but I wouldn't use anything else because of it's excellent coverage.

Thanks for sharing your thoughts and opinions...we can all learn from each other.
