Set #2 offers a variety of smooth incuts. There is some organicness going on with the incut as there are some ever-so-slight fingertip impressions. The kind that gives you that little extra boost of confidence in them.
Compared to Set #1, they are slightly bigger yet slightly more challenging. The difference between this Set #2 and Set #3 is that #3 has a crease shaped into the incut. This set has a smooth incut, which is ideal for long training sessions.
Set #2 is an excellent choice on vertical walls for beginners to prepare them for harder grades. For the hardcore, expect soft V6 on a 45-degree wall.
