I ordered the whole XXL Split Ledge series in white to serve as shared hub features that multiple problems could incorporate within the limited real estate of a training wall. Currently they're on my 25 degree board in diagonal orientation for tricky, high body tension match moves. Would also be great for compression problems. #1 is half and half in terms of positive/slightly slopey. Oriented vertically, you can definitely get the thumb involved for a pinch. Super versatile.
