I will be going to a competition in 2 weeks. I wanted to get a better cube than the one I have currently own(YJ Chilong). I average sub 30ish. I like smooth/crunchy/buttery cubes, but not sandy ones like the Fangshi Shuangren V2. I will be using Calvin's Lube on them. Which cube would be good for my speed?(I cannot get a Yulong because it is only available in stickerless where I live).
