@ CHR : In terms of your elbows hurting on the metolious strips, why not cut them in half and angle them a bit wider and more friendly for those elbows :].
At our gym we t-nutted in grid fashion a floating 15-degree 10 ft wall. With that I set campus routes weaving in and out of the Metolious campus rungs and Nicros system boards. The Nicros system pinches are awesome on a 45 degree wall as well.
We also offer rings for training and Grip tape covered PVC pipes for each hand that float on a smaller metal pipe-pull-up bar that hangs from the ceiling. [Great for being able to hoist it up out of the way when not in use] These tools can provide upper level training for core and forearms, and double as a fun thing for people of all experience levels to try out.
