That's a great sized space for a home wall. Now you're talking! That extra bit of headroom will really make a big difference.
You tend to get a lot of questions on here about college projects and surveys...
If you're looking for power and strength, it's simple enough. For endurance, you need to be able to create sustained laps, which essentially means circuits which don't have massive peaks or troughs, no rests and which can flow. So you need more of a 360 arrangement on the vertical, and enough space on the horizontal to isolate moves - which, with a 12 foot width, you've got in spades.
Looks great - you've got the basics (without volumes). If you have 12 feet of width, you could run out two overhanging panels, side by side, one steeper than the other.
It's going to cost a few grand, though - you know that, right
