While it is not obvious to the eye, set #2 is definitely a step up in difficulty from set #1. I have a few of set #2 mixed into a problem with set #1 on a 35 degree wall. I would say this mix of holds, even with positive feet, yields a V5/6 problem, at this angle. I have them set in their most positive orientation and not too far apart. You could easily amplify the difficulty by changing either of those factors. I am also using a few of these in combination with set #3 on a 13 degree wall, which also feels V5/6 with small feet and more dynamic movement. The various progressive series of holds in the Golfus line really allow you to dial in the difficulty at multiple angles.
