The differences in positivity on the various series of small Golfus crimps are visually subtle, but they feel markedly different on the wall. Series #1 feels like a V4/5 hold to me on a 35 degree wall. The shape is like the baby sibling of the medium Golfus edges steep wall holds, offering a nice progression in difficulty from that series. I find that these holds have me wavering between a 3 finger drag and a 4 finger half crimp on steep terrain. Each hold has a thumb dimple on the surface opposite the crimp. The dimples feel directional on different holds, i.e. some holds feel a bit more tailored for right or left hand. This can factor into where I choose to place them in a route, but all holds can be used by either hand comfortably.
