Thanks for the welcome and info Procharged. CF isn't cheap is it? $300 for an 1/8" x 1 1/2" x 48" angle, WOW! The first place is near me, I may try them in person and see what I can find. I may have to go aluminum simply from a budget stand point.

I'm going to go forward with the sigle sided design on the batts. Thanks for the input Brian!
