Probably won't change the screen until I upgrade the projector...still very happy with it so no plans to do so. Added a second ULS-15 as well as a pair of SVS SB12-NSD subwoofers and the AS-EQ1 sub equalizer. Flat response and lots of air! Added the S15 for "critical" components. Upgrading main BP7002's for a pair of BP7000's in the works.
Improvements: Going with a Stewart 1.3 gain screen material; Updating the DVDO Edge to a DVDO VP50 Pro (VP30 at a minimum); What are your main speaker model #s?; 2nd sub always smooths bass response in a room; Replace a number of your power tweaks with a single APC S15 or S20 to handle current filtration, battery back-up, etc. for the projector and all source components.
