Hi I've been playing tennis for a year or two now but just started getting into competetive tennis now. I need a new racquet and I've already decided on one (Prince Ignite Team) but I don't any idea about strings. I'm a freshmen in high school and I'm 5'0, 103 lbs, so I'm not gonna be breaking strings often. What string will last me about 4 months that will keep tension? Also could someone explain how long each string types last? Like polys, multi, synthetic, natural gut, etc.
