This is an excellent feature hold for beginners on low-angled walls. It offers 2-1/2" to 3" wide pinches, which is the most comfortable for most adult hand sizes. You can expect V1 on vertical walls and V2 on 25-degree overhanging walls.
You'll love this hold on a 45-degree wall as the lip of the hold flattens, allowing you to hang your fingerpads on the lip rather than purely squeezing down on it. The lip is incut, even on a 45-degree wall.
To get a crimp rail out of this hold, I orient it hold horizontally with the incut on the top. I set big enough dynamic moves that force you to bring the hold down below your shoulder. Setting the hold this way requires a more extended reach to grab the next hold successfully. If set correctly, you will not be using your thumb.
It's worth trying because the crimp rail feels like granite bouldering outside. Just like fractured scooped-out granite, the best part of the crimp is on the lip of the hold.
