I also built mine around the L e v e l d and with the interfaces of Open cockpits. I stayed with FSX, because there was no 767 for P3D. So I am happy that the CS one is now availble. I allready reprogrammed all my buttons, switches, rotaries and lights to use with CS767. It is all working fine now. Although I would like to be able to write directly to the IND´s from SIOC. However, CS does not allow that. As a result, the Rotary encoders do not run as fine as in the another company.
All I have to program now is my self-built FMC.

Besides, your setup looks good too!
