What are the J-200 strings like, gauge-wise? I have a jumbo-body Yamaha, and keep it strung with D'Addario Bluegrass gauge. They're slightly lighter on the top and slightly heavier on the bottom. Seems to me they help maximize the big fat sound of a jumbo. If I could afford a J-200, I'd get one in a heartbeat. Until then, maybe the J-200 strings are worth checking out.
