I added these to the 60 pack steep wall set, for my 45 degree wall. As the 60 pack steep wall set is ~V3 to V5, these are great for mixing in on a route to make them v1 and v2.
If you just used this set on 45 degrees, it would be mostly v1, unless you made it reachy or poor feet.
The one pocket jug is just two fingers, if you have larger fingers.
