Zandor,

Just two more items then I think I'm good for now.

Re: Light reflectivity.

I am using this one-side-white masonite which is semi-glossy.
A spray of Flat White is better than mirroring effect of glossiness???
Is this an absolute?

ReflectorHood will duct out top at center and be fashioned from 12" wide roofing flashing. Just one simple long arc left to right.

How advangageous / important is it to get some front/back down-angulation built into a reflector? (a la batwings, as it were.)

Anyone's tips appreciated.
