Variety is the theme in this set. One is a wide incut rail, another is a two-handed flake, and the third offers a steering wheel-like orientation. Think hands at your 10 and 2 o'clock positions for this third hold.
The incuts range from 45 degrees incut to 60 degrees incut, which means they will stay a jug on all angles of walls except roofs. The flake-like feeling design is the only one that could be used in a roof feeling V6/7 at its easiest.
The granite texture and design on the incuts match the face of the hold, so you can expect to find where you want to grip just as you would when outdoor climbing.
