The problem with this arrangement is that, due to the control panel on the lower P'08, the upper P'08 cannot be pulled close enough. I would prefer to have the proper two-manual organ/Prophet 10 arrangement, with one keyboard immediately over the other. That way, you can easily play notes simultaneously on both manuals with one hand. This has many musical advantages. So, I would prefer a DSI Prophet 16 to two Prophet '08s.
