Well than maybe the 55mm would help all around, not just in OH! Try it out but if you know someone who has a 55mm, try theirs out first before you get the CZ.
My birthday is in a month. I am trying to think of what to get puzzle wise. I want to get a speed stacks timer cause I don't have one. Where is the cheapest reliable site to get one? Also I have 2x2-5x5, pyraminx and square-1. Which WCA puzzle should I get?
What is the absolute best speed solving cube brand to use for the 4x4. Im not even sure if v-cube makes 4x4 but if they do, i cannot find one anywhere. I currently have a shengshou 4x4 and a lanlan 4x4. My shengshou pops on occasion, i know most cubes will pop on occasion but shengshou 4x4's have a ton of pieces and its difficult to put back together. The lanlan 4x4 has a ball core, but its corner cutting is terrible, not to mention its giant.
