Hi, I'm Ivor Savage owner of YTEX High Performance Tennis Strings. We are based in the beautiful city of Savannah Georgia USA and this place I've been blessed to call home for the past 18 years. You might ask, what make YTEX different from all the tennis string brands on the market today? Well, its very simple... we specialize in very soft co-polyester strings which is easy on the arm. We care about players and their well being on the tennis court so we designed these softer strings to help players make the smooth transition from synthetic gut to polyester strings without the discomfort that normally goes along with polyester strings. Our co-polyester strings are made in Germany and our synthetics in Taiwan so we only carry the best of the best. If you want to know how YTEX compares to other brands, just have a look at the "Reviews" from over 300 customers with over 95% giving YTEX 5/5 Stars. The USRSA (United States Racquet Stringers Association) has ranked our flagship string the Quadro Twist at #1 for spin & #2 overall out of 200 strings they blind tested. We are only second to natural gut which is at a much higher price point. I myself play at a high level, former 10.0 USTA National Mix Champion and I cannot imagine myself playing with any string other than YTEX. If you are open to change, then you'll be pleasantly surprised when you try YTEX.
