Valk 2 M
The Valk 2 M is an amazing Pro-Level 2x2. Out of the box, the Stickered 2x2 actually turns better, but after some setup, you can make both of these cube great. This cube is definitely recommended for cubers who want to up their 2x2 game. You can also get this cube in a bundle, with the Valk 3 M and Valk 4 M, which are both also great cubes.
