Donny, Tilt screen , YES !!!
Except that your mic is on the opposite side, your KB setup in the pics looks just like mine ...
From
MY experience, I think your evaluation of the Pa900 screen as "horrible" is overkill ... granted, I don't have a S970 to compare it to, but as I said, my experience with the Pa900 has been fine with the rear of the board raised just about an inch, and yes, when I am gigging I sit higher than you ... of course there is a problem in direct sunlight, but that happens with any board ...
One would think that after all this time SOMEONE would have come up with a way to see ANY screen - phone, tablet, KB, whatever, in any kind of light ...
I am just glad that we both have KBs we are happy with - at least to some extent...
