I'm sure this has been asked before, but I can't find it.
My 3x3 average is about 20 seconds. I have a Dayan Guhong, but it's run out of Lube and people tell me silicon spray won't help a Guhong. I'll probably go for a Lubix cube, maybe a Lubix Zanchi or LunHui, I really don't know though. Any 3x3 suggestions?
Also, I'll probably buy a Lubix Whittwo (don't know the spelling), good or bad choice?
