You are correct sir. There are so many polyester strings that will help in the low power, spin department, so it can make be confusing as to which brand to use. Solinco polyester strings, as the previous poster stated, is a good area to start. I would suggest Tourna Black Zone (16g) because it is the least expensive, durable and low powered string that I have used. The importance of having an inexpensive poly string is due to the fact that you must restring them every 15 hours or so because they become too springy, and you will lose the control that you had when they were fresh. Depending upon your age and skill level, you may also find that polyester strings could cause arm soreness. If that's the case, then you will be forced to use a synthetic gut string at high tension. Unfortunately, you won't get the spin and control that you would from poly strings. Good luck and enjoy your tennis.
