From the Gold-Label Viscaria's Green Plastic to the Cyber CWT's Weights

Quite a few players probably know that the handles of some gold-label Viscarias have green plastic added inside them.

But not all of them. I’ve seen some FL handles with it added and some ST handles without. Whether it’s entirely consistent, I can’t say for sure. (I don’t have the money to take them apart one by one to show you, do I?) So what role does this green plastic block actually play?

The most straightforward view is “adding weight.” For instance, if this batch of gold-label blades came out light, then adding a plastic block to increase the weight is perfectly normal. In fact, there are similar practices on other brands’ blades, too.

Another view is balancing the center of gravity. Suppose they originally planned to make a hollow handle — then temporarily adding a plastic block both increases the weight (too light a blade hurts its market price and market valuation) and shifts the center of gravity a bit toward the handle.

And the most ideal idea is this: while further improving hitting quality, you still achieve a good blade center of gravity. In other words, although it looks heavy, it doesn’t feel that heavy to play, and the hitting power is even greater.

Through a deeper understanding of the Cyber CWT technology, I came to realize this point.

What was the original intent behind creating four weights of the Cyber CWT?

The CWT (adjustable weight technology) that appears on the Cyber 6 and the all-wood Cyber gives the blade four weights to choose from. Besides the base version with no added weight, there are three more: 3 g, 6 g, and 9 g.

Choosing different weights can achieve…
