Gonna start my home wall project soon. I’m thinking 8x12 or 8x14 with a one foot kicker at the bottom. Is this plausible? Attached is the planned location, about 9ft of clearance. I want it adjustable to 40° but I probably won’t go higher than that because of the risk involved lol. Is there anything I should know beforehand? Is it even possible? Can it support itself with the weight? And where can I get hella climbing holds at a good price? Please tell me anything you can. Thank you.
