Well, finally finished the basic "board" part last night (still have to run the power, add the front bindings to the tiers, finish painting, etc.) so I wanted to try it out this morning as far as using it on the floor and how it feels. Tossed a bunch of pedals on it and it is not bad at all! The rear tier is only 4.75" off the ground.
Figured I snap a couple of pictures while I was at it. Note that this is NOT the way the pedals will be laid out (most of them aren't even straight in the pics), just a bunch of random pedals tossed on to check it out.
