so the next question now, is what shape to build a modular wall attachment? I'd like to add a large feature to bolt holds on to change the angles of the wall a bit. something like this or this. I'd like to know if any of you have created/climbed on modulars like these and what shape was good for climbing on. Just looking for ideas and tips before I start building it.
And, for the Corvallis folks around, we are climbing in the cave most Tuesday evenings and I'd like to extend the invitation to all y'all to come and climb!
