Gamma Twist technology

Two new Gamma strings use a process through which texture is added by twisting the string during the manufacuring proces. One is the Zo Tour Rough, which is "rough" because of the twisting. The other is a pentagonally shaped co-poly which is then twisted; it's called Zo Twist.

I've been using the Zo Tour Rough, and really have been enjoying it - I rated it on stringforum.net. About the same spin potential as ALU Rough, maybe more, and almost the same control, certainly more control than the different pent, oct, and hex shaped strings. Softer and more comfortable than ALU. Lower power, too. So between the softness, lower power, and texture, it's a great string to make stiff, powerful racquets like the Extreme Pro or Pure Drive/Aero Pro Drive more comfortable and control their power. When you think about the Zo Tour composition, it appears that the new Luxilon M2 mimics it - a poly with elastic strands molded into it, running its lengh. My understanding is that Zo Tour has six elastic strands while M2 has 5. The Rough version then takes the Zo Tour string and seems to mold it in a twisted shape for texture.

The new Zo Twist, a pentagonal string with this twisting, is of particular interest to me because it may help with what I have observed to be a control problem with shaped strings. The edges of shaped stings are not all facing the same way, so "bite" on the ball is inconsistent from hit to hit or on slightly different areas of the racquet face. By twisting the shape, whether its pent, hex or oct, there is consistency through the racquet face. I just strung one of my racquets with this new Zo Twist and will try it tomorrow.

I have a question that maybe someone could help out with. The packages on these two new Gamma strings say Made in England. Does anyone know who is manufacturing them?

Thanks!

Gamma is probably distributing strings from some English company, who no doubt gets it from China. England does not make strings.

The package says - Made in England. Generally, when a product is made one place and then distributed by a company somewhere else, that company will list where they are located (and sometimes this seems to be done to have consumers thiks it is made there), but I'm fairly certain that trade laws prevent that company from saying "Made in ..." So, I here you loud and clear, and it is a good point, but maybe there is some manufacturing going on in England that is new or not commonly known of. It may not be a tennis string company, but instead a medical tubing company or textile string company, which I think is what Luxilon originally was and still is.
