Hey，I am Xingye Zhu from China. I have been using zz method for 2.5 years and I am still practising. I can solve the cube in 12 seconds speedsolving and 17 seconds one-handed. I am very interested in zz and I want to exchange experiences about zz with you(are you still cubing? I have noticed that you didn't compete in this year). My e-mail address is [email protected] Reply me, please.
