Okay I've been speed cubing for 3 months and sit at a solid average of 40 seconds with a ebay bought zhanchi. I also own all the other dayan's from puzzle addictions, my zhanchi is my main cube with guhong v2 as my OH, I have lubed it and want to get a new cube which will better my zhanchi. I was thinking of the ultimate lubix zhanchi, or the camcuber zhanchi I just don't know what maybe better, or I don't mind spending $100 on the elite lubix zhanchi, though my times maybe decent it is my recognition of f2l which takes me about 30secs on avg. Also I own a mefferts pyraminx and haven't lubed it yet, should I stay with mefferts or get a shengshou.
