Hi, I've played with Prince rackets for many years but because the mains are 16 rather than 18 I break strings often. When I played with the Graphite XB the strings would last longer than with the Graphite Triple Threat that I currently use, but the XB got a little too heavy after two hours on the court. So, I've been on a long journey to find the best strings when considering price, pop and longevity. The best I've come up with is using Luxilon ALU for mains and Laserfibre tour for crosses. This combo gives me 12-15 hours before the strings break. I guess my options are to buy a racket that uses 18 strings for mains or to keep my Prince and buy a stringer for < $200. I think I'll keep the Prince and buy the stringer. I do like it but it's become a hassle to constantly get it strung. Anyway, I know 18 strings for mains would increase longevity considering everything else is equal but what are the differences (if any) with how a racket with 16 mains would play versus a racket with 18 mains. Thanks.
