I want to buy a new ball core 4x4. I already have a shengshou version 1 and I like it, but it's too hard to put back together when it pops and I just wanna try something different. I've been thinking about a Dayan+mf8, but it's too big for my small hands, I've heard a mini QJ breaks too easily, and the LanLan is also big and not that good. What should I get? (It doesn't have to be the ones I listed.)
