I feel like getting a 2x2 cube and a 5x5. I like a smooth cube that won't overshoot, it won't have to cut corners over 10-15 degrees on the 5x5 cubes, but maybe on the 2x2. I also don't want to mod my cubes to make then perform well. For the 2x2x2, I'm thinking of getting a Lubix Wittwo, and I'm thinking of either a V-Cube 5 or a Shengshou 5x5.
