I am looking at trying out a set of Luxilon strings. I am afraid I will really like them - afraid because I cannot really afford to use them. I have played with Ballistic Polymono 17 for over 10 hours and they still have plenty of life left in 'em, not sure I will be able to break them any time soon. What kind of durability (tension maintenance, playability, breaking) can I expect? But, my main thing, I hear they have good durability so I want to try an 18g string and TiMO and Ace are the only two Luxilons that come in 18g. Any feedback on one, the other, or both is appreciated.
