I will 2nd the stay away from studio. It has come along way this year but I would not use it for a customers system. Still to many open issues. If your using system builder stick with it. There are button models that still are missing in studio. Press and hold doesn't exist. Really. Still.
On a side not I have my entire office building running on a pretty large "HYBRID" program. I setup all the simple programming using macro style and did all the lighting, navigation, security, climate, in program designer. The processor is a PRO2 and I have several 2 series and 3 series panels.

(4) Mobile proG
(4) Crestron APP
(1) Xpanel
(1)Smart graphics X-panel
(2) 4 inch touch screens
(1) 8 inch touch screen

Funny thing is I still need to change out my processor and the series 2 TP's. Just haven't gotten a chance. The Crestron app ipads get used more than anything else.
