This rail is for the beginner on vertical walls, feeling no less than V2, and for every other level on anything steeper. In slightly overhanging 25-degree terrain, you can easily set V5 through V10.
On a 45-degree wall, this hold at its easiest is V8 while setting with heel/toe cams, but otherwise, this feels more in the V10+ range.
The slope on this rail has an organic flow rising and dropping down with no discernible sweet spot. The angle of the slope ranges from 15 degrees to 40 degrees, which gives a massive amount of flexibility on where you can set with it. This flexibility also adds variability when you hit it. There is no obvious best spot, so if you have multiple problems crossing it, you might prefer different locations on the hold to navigate each problem.
This hold is half of our Granite Crack Sections C and D. Technically, this hold is Section D.
