Fangshi cores meant for the other side?

[CoreSwitcher]

So, I mentioned earlier today that the cores for each of my fangshis were different. However, I realized that when I sqitched them, they somehow turned better. The black one suddenly didn't jam up as much, and the white one started to move in a much more smooth, less jerky, motion. And it also looked cool.
So I recommend buying 2 fangshis, one white, one black, and then switch their cores.

The color of the Fangshi doesn't affect the core...unless you got a bad order or something.
Also, neither the color of the cube nor the core really affects the performance. Maybe you're referring to the centers?

I'm using a Dayan Core In my shuangren, I wonder If thats why it has trouble cutting over line to line?
