String Playtest: Genesis Typhoon 16L

Genesis Typhoon is available in 16L in battleship gray and twilight blue and comes in sets of 40 feet or reels of 660 feet.

Genesis Typhoon is recommended to the competitive and professional players who demand the absolute highest levels of power, spin, feel and control.

Typhoon is a five-sided monofilament poly. It is made from a proprietary composite formula of high-tech polyester resin combined with new performance-enhancing chemical additives and aluminum fibers.

Genesis tells us that after extruding Typhoon, it applies several heating and cooling stages. Typhoon is then additionally twisted axially for maximum bite. A coating of Teflon increases the liveliness and offers a nice crisp stringbed.

Over 30 colleges are now playing with Genesis strings, including two-time defending NCAA national champion USC, University of San Diego, Texas A & M, Portland State University, George Washington University and many more.

Genesis strings are now being distributed through many countries including USA, Mexico, Brazil, Argentina, Spain, Japan, South Korea, and Australia. Genesis believes that Typhoon's price/performance ratio is unmatched in today's market.

Typhoon is available in 16L (1.26 mm) in Battleship Gray and Twilight Blue. It is priced from $9.90 for sets of 40 feet, and $118.90 for reels of 660 feet. For more information or to order, contact Genesis at 888-750-1011, or visit genesis-tennis.com.

In the lab

We tested the 16L gauge Typhoon. The coil measured 40 feet. The diameter measured 1.25-1.29 mm before stringing, and 1.22-1.24 mm after stringing. We recorded a stringbed stiffness of 73 RDC units immediately after stringing at 60 pounds in a Wilson Pro Staff 6.1 95 (16 x 18 pattern) on a constant-pull machine.

After 24 hours (no playing), stringbed stiffness measured 67 RDC units, representing a 8 percent tension loss. Our control string, Prince Synthetic Gut Original Gold 16, measured 78 RDC units immediately after stringing and 71 RDC units after 24 hours, representing a 9 percent tension loss.

In lab testing, Prince Synthetic Gut Original has a stiffness of 217 and a tension loss of 11.67 pounds, while Genesis Typhoon 16L has a stiffness of 237 and a tension loss of 20.64 pounds. Typhoon added 15 grams to the weight of our unstrung frame.

The string was tested for five weeks by 37 USRSA playtesters, with NTRP ratings from 3.5 to 6.0. These are blind tests, with playtesters receiving unmarked strings in unmarked packages. Average number of hours playtested was 27.8.

Genesis Typhoon feels thin for a 16L string, and there is no question about it having a polygonal cross-section — or about it being twisted during the manufacturing process — when you see it. Typhoon has what might be called "coil memory," even though its tendency is that it wants to be straight, rather than coiled. Typhoon glides nicely for a twisted, polygonal string, whether you're pulling the crosses across the mains, feeding it through an angled grommet, or cinching up a knot.

No playtester broke his sample during stringing, 10 reported problems with coil memory, one reported problems tying knots, and three reported friction burn.

On the court

Our playtesters forgave any issues with stringing Typhoon once they hit the court, ranking it 10th overall of the 147 strings we've playtested for publication for Spin Potential, and well above average for Durability, Resistance to Movement, Tension Retention, and Power.

As a result, Genesis Typhoon's overall average score was also well above average. Because Genesis recommends Typhoon for competitive and professional players, it shouldn't come as a surprise that playtesters with NTRPs of 4.5 and above and/or playtesters who normally use polyester strings gave Typhoon higher marks than the rest of the playtest team.

Conclusion

When playtesting a poly, you expect the playtest team to comment favorably on the string's spin, resistance to movement, and durability. You don't expect raves about the feel and touch, yet that's exactly what several of our playtesters did.

With the publicity about poly strings these days, tennis players of every age, shape, and description are considering trying them. According to our playtest team, Genesis Typhoon is one you could recommend even in cases where there could be issues with arm sensitivity.

Another one of Genesis Typhoon's strengths is its tension maintenance. In our 24-hour stringbed test, it lost less tension than our benchmark nylon string, and several of our playtesters praised this characteristic.

Playtester comments

"The feel is outstanding." 4.5 male all-court player using Wilson K Six One (68 Holes) strung at 55 pounds LO (Wilson Hollow Core Pro 17)

"This is a responsive string with an excellent feel." 5.0 male all-court player using Prince EXO3 Black (port inserts) strung at 58 pounds CP (Prince Premier LT 16)

"The texture enhances bite. This string has some serious spin potential." 4.0 female all-court player using Prince O3 Tour MS strung at 58 pounds CP (Tecnifibre NRG2 16)

"Typically, I do not prefer a full poly setup. However, this string has surprising levels comfort, power, and touch. My strategy of using a lower tension really paid off." 5.0 male all-court player using Babolat Pure Storm LTD GT strung at 53 pounds CP (Natural Gut 16)

"This is a great option for hard hitters. No shortage of bite." 3.5 male all-court player using Pro Kennex Graphite Acclaim strung at 57 pounds CP (Wilson Natural Gut 17)
