Arrow Especially.........

Especially if the Blast was left in the racquet too long. RPM has an approx life span of 4 -8hrs of play depending on the players level. The stronger the player the shorter the life span. Check the tension in the racquet and I can guarantee that the string have lost 16-20lbs from the original ref tension. Poly strings do not have a ery long life span in general, but they are good at what they were designed for.

Cheers, TennezSport
