I have built 2 home walls, the first one was an adjustable angle wall and worked out really good. That way I could adjust for crimp and sloper problems. That wall was a single in a garage, I moved so now I have a cave set up in a barn type shed, with a mix of vert, 60 deg, overhanging and vert with 70 deg at top all stationary. I like the adjustable the best, I couldn't do an adjustable with the ceiling height in the shed. Either way it is like having your own private boulder.
Have fun.
Plastic to the people!
