Dual textured panels force moves on to the crystal and panel opposite. Not a foot hold when trying to stand on the Dual Textured panels. Great for forcing specific moves. On low angles, you can use the crystal for a beginner to intermediate level feel or flip it and get hard out of it. It gets extremely hard as the wall gets steep which makes it an awesome power endurance hold. We like setting with two of these opposing to get in some compression training.
