This set of 5 holds consists of comfortable one and a quarter to one and a half finger-pad deep pockets. They are the next size smaller in the Golfus Pocket Line when compared to Set #2.
In this set, there are:
2 x 3-Finger Pockets (Easy to grip for most climbers)
3 x 2-Finger Pockets (Considerably harder than the 3-Finger)
The three-finger pockets in this set are the most incut. The incut is just shy of one and a half finger pads deep. They feel V1 on a vertical wall, and some will consider these big enough to call them mini jugs.
On a 45-degree overhanging wall, the Golfus divots located on the incut add even a little more depth and positiveness. So, when your wall angle is at 45-degrees, you will still have an ever-so-slightly incut pocket. They feel in the V3 range.
The two-finger pockets are substantially harder than the three-finger pockets in this set. The average two-finger pocket is one finger-pad deep, half of a finger-pad smaller than the three-fingers. Using these on a vertical wall, this depth is an excellent introduction to learning how to grip a pocket with two fingers. When these are used on a 45-degree overhanging wall, the shallowness becomes apparent, and the difficulty increases substantially to V6. The incuts range from neutral, to 5-degrees incut, to 10-degrees incut. This means in steep terrain, the pockets are down-sloping.
A surprise in a good way is that there are smaller holds designed near the bolt hole. So the Expert might take a look at these "Flip Side Pockets." They range from 3/4" to 1" deep, which is a full finger pad. The Flip Side pockets are smaller versions of the positive parts of these holds. They will feel V2 on vertical, and on a 45-degree wall, they will feel in the V7 to V9 range.
The Spinner Screw is a nice design touch as well. Since the climbing hold won't spin, it is an excellent choice for outdoor and playground climbing walls.
