I know full pll and like third of oll. I ordered a Qiyi thunderclap v3 M, but I still haven't received it yetNever ever rotate during cross, it really slows it down. Try posting some example solves on the Solve Critique Thread so that we can see how efficient your F2L is. I'd start learning full PLL if you don't already know it, then move onto OLL. You can get a better cube if you want, the Qiyi MS is only 9 USD
