XXL Facet Rail #3 has one 5" wide section that has a 5-degree incut, otherwise, this hold is neutral to slopey. The boomerang shape is cool in that when you set your problems, forcing a cross-over on it, the contour of the hold creates a nice flow for the move. The hold sets itself in a way.
This is not a beginner's hold. This is a V3 hold on vertical, V4/5 on 25-degree walls, and V7+ on a 45. On a 45-degree wall, you can expect to be pinching this hold. The widths when pitching range from 1-3/4" to 2-3/4" wide.
