Hopefully she's not gigging five nights a week with that RD-700?

You're right though Kingfrog. If each individual key had a 3 oz. weight that would be 16 1/2 lbs total for 88 keys. If each individual key had a 2 oz. weight the total would be 11 lbs for 88 keys. You have to account for the spring mechanisms as well so it does add up. I'm not sure what the considered "normal range" of weight used in weighted keybeds for workstations or digital pianos is but I wouldn't think it would be over 3 oz. at best and most likely a lot less than 3 oz. and more like 1 to 2 oz. If it were only 1 oz. then the total would be just 5 1/2 lbs additional weight for 88 keys. The actual keys themselves are not made of wood on any workstation or digital piano that I'm aware of, rather, they are made of fine molded plastic materials and which as a result make them fairly light.

Best,
Mike
