As Atomik states, these are more challenging than set #1. The two sets mesh well together. I use these on both my tall low angle wall my 35 degree woody. They start at V5 on the 35 deg wall with the "easy" side up. These will definitely work your sloper technique and force you to whip that core into shape. I paired them with set #1, the XXL Font sloper, the XXXL Font pinch, and 10 small cobble feet. This is a super fun combo that offers a ton of setting options.
