Thanks! The playability and ergonomics are good up to about 12th position in my usual pose sitting down, but better if on resting on left leg. That's just bad design on my part as the leg rest area is way too high up. On a strap though it's all good. It's all flat btw, the board and neck profile. Much more comfier than it has the right to be. Maybe some day in the future I'll redo the design, but that's not the very near future as I have other things to do.
