While I would like to be able to stand while performing, physically, this is not an option. I agree with UD and Donny, about the positive aspects of standing, however, usually when I try it, by the end of two straight hours, both my back and feet are shot to hell. I also use a foot switch, one with three buttons, but I'm in the process of building a miniature version of the switch that will attach directly to the keyboard via a velcro strip. I did this with a foot volume control for the PSR-740 and it was the best thing since sliced bread.
Within the next few weeks, I headed to south Jersey to meet with Donny, listen to his powered speakers, then after picking his brains, I'm gonna' revamp my entire system, lighten the load, and try to come up with a setup that permits me to be at or near eye level with the audience by using a mid-height stool with a backrest. (I'm getting too old for this stuff.)
As for moving the equipment from the vehicle, I must agree, lifting from inside a car trunk is bad news for the back. Sell the Rolls and buy yourself a full size van, or even a mini-van. Then can hold an enormous amount of gear, they ride well, gas milage sucks, and they're easy to load and unload. My house is 165 feet from the end of my driveway, therefore, I hook up a 10-cubic-foot garden cart to the lawn tractor and haul the stuff from the house to the van using the cart. Lugging a 90-pound speaker that distance, uphill, even with a refrigerator dolly, is tough on the body parts.
Good Luck,
Gary
