This set is not just your ordinary run of the mill pinches. With their curved lines and divots, slight rotations will allow you to get just the right difficulty you want out of the hold.
What we like these holds best for is hand matching. When moving from one direction and forcing a hand match sequence on them, the variations lends for some really interesting hand positions.
They are very easy to set with to get exactly what you want. On vertical, expect V2/V3 feeling holds. On steeper terrain, expect nothing less than V5/V6.
