I'm having a problem with my left shoulder and I did notice that playing the 3/4 yesterday evening did not bother it. I ended up playing another couple hours after I got home and my arm/hand is no worse today than it was before all that playing.

This new one is LOUD (and ugly)

I hope you do get the Luna and that you end up as pleasantly surprised as I am with my purchase. It's heartbreaking to have to choose between Hurting and Not Playing.
