When you are looking to fit some holds into the spaces on your wall, medium-sized climbing holds go a long way. The incuts range from neutral to 15-degrees which means there will be a challenge for beginners on vertical walls. You should expect between V6 and V8 on a 45-degree overhanging wall.
Each hold is different, giving you the variety you want.
