Per Atomik's recommendations (email them with questions, they are super helpful and friendly!), I got this set in combination with some limestone and dripstone jugs, to setup my wall. I also got a 12 pack of small footholds, for the kicker.
My wall is a 45 degree angle, with a 12" kicker, and on one side, a vertical, and then a small roof section that I ended up ordering a roof set for.
As advertised, this set gets you going with a v3 to v5 on 45 degrees. The basic crimps and medium pinches are definitely v5+, which I'm still working back into, so for now I'm using them on the vertical section as side and underclings to build my strength.
The steep wall slopers work well at 45 degrees and the variety of holds make it easy to set different styles of routes.
Overall: A great foundational set, if you're first setting up a wall, which will give you a good idea of what you need more of, to fill it in.
