Thanks!

btw, why not leave an airgap behind the wool on purpose. It'll improve your low end trapping slightly  |
Not sure if I fully understand your thought here but I'll just mention a few things:
The design of my trap includes a 0.75" air gap behind the 703 fiberglass. And I'm adding polyester batting to the top 0.75" to kill any reflections that might bounce off the plastic sheeting that will be wrapped around the 703.
In the room I'd space the traps away from the wall as opposed to screwing them directly to the wall, but the room is so small that I simply do not have the space to be able to do this. As it is, with the traps being 5.5" deep, placing them directly on the walls, I am losing a full 11" of width and length from the room, and losing 5.5" of ceiling height. I wish I had the room to hang them several inches out in front of the walls etc, but then I wouldn't be able to fit my gear in there! Yes, it's a SMALL room.
What I find interesting here, because small rooms can have such serious close-reflection issues, it seems that one needs the same amount or maybe even more bass trapping per square foot with a small room than with a larger room. Close-reflections can cause BIG problems (as I have observed first-hand) and MUST be eliminated in my opinion.
A friend of mine stopped by and saw all my trap frames and commented that my new room must be really huge for me to need all those traps... but in fact, the room is very small.
I plan to pretty much cover the entire ceiling with traps because the ceiling is low and the floor is a solid concrete slab. Bad enough I will have heavy reflections off the floor, but the last thing I want is standing waves between the floor and ceiling and general close reflections off the ceiling, etc. I want the ceiling to disappear... so I will cover it about 85% with my 5.5" traps. If I had more ceiling height I would have made them even thicker.
Walls too... will probably cover easily 80% of all wall surfaces with the traps. It's not that I specifically want a "dead" room, but close reflections cannot be tolerated. So it's gotta be "dead". I'd much rather have a dead room than one with wacky reflections and a horrible "small room sound". Once a "small room sound" gets on your tracks, it's there to stay no matter what you do, it's so critical in my opinion to make sure that when tracking, you're either in a good room or one that is well "trapped"... that is if you want to have any chance of yielding a pro-level production.
Considering my small room situation, it wasn't necessary for me to make all these frames. I could have maybe just screwed the 703 right to the walls and just hung blankets or curtains in front of it all, etc, would have saved a lot of time and work, but my feeling is that I hope to not be confined to this small room forever, hopefully things progress and I'll be able to get myself into a larger room in the not so distant future... thus by having my traps built nicely with frames etc, I will be able to move them very easily and quickly... and even now, if need be I could always just pull a few off the wall to bring to a remote location for recording, etc... makes the whole situation a lot more flexible.
Plus, the frames will ultimately allow me to mount the traps with very few holes into the walls. I will explain my ideas and post pics once I've hung the traps... but, in sum, my plan is to add three long "beams" to the ceiling, two brackets on each beam (total of nine bracket on ceiling and thus a total of hopefully just 9 holes in ceiling), from these three "beams" I will hang a whopping TEN of my 5.5" deep, 4'X2' traps. Nine small holes to hang ten huge traps, not bad I'd say... but the trap frames make this possible and reliable. I really don't want a lot of holes in my nice new sheetrock.
