Until now I'm very confused with those terms. Does having bad tension maintenance necessarily mean the string is easily-turned dead? Or those two aren't really related, or even not related at all? I don't really mind having my string's tension decrease 10%-15% in a month without much change in liveliness and power, however I do mind if my string goes dead even though the tension doesn't change at all. OOT question: In my case, which string do you suggest to buy: SPPP or Polyspin Energy?
