Tamca 5000 vs ALC

Tamca 5000 blades are stiff and powerful. As a result , they have high reaction property.  If you look at the this butterfly blade matrix, you will see that Tamca 5000 blades such as Butterfly Sardius and Zhang Jike T5000 are in the higher end of the Reaction property axis of the graph. This is a testament on how fast Tamca 5000 blades.

On the other hand, ALC blades like Fan Zhendong ALC have a good balance between power, speed, and control. Again, on the matrix you will see that ALC blades are somewhat on the middle and have lower vibration properties (good control).
