I would really like to just fold mine, less cost, but I tryed that and every time I pulled out fabric i had to either wrestel with the fabric on top of what I wanted and restack or refold at least 2 pieces I didn't want. I find I really like the boards. Nothing comes unfolded, nothing is stacked above or below what I want. With shelves that deep you may be able to run a second row of only 6 inch high bolts infront of your taller bolts if needed. Personally I don't like the second rows because I always want that one piece way in the back, and have to move the front bolts anyway! LOL
