i love this string because im quite a hard hitter so its good that the repulsion is not as strong as the other stings. also this string LAST A LONG TIME!! i had it strung 2 my carlton airblade tour... my carlton snaped sure game play but the strings were still good. also i have it strung to my yonex MP and its been like 7months. i play 3 times a week 4 close 2 2.5 hours each time. And its still there.
