I tried PPA 16 black for the first time. I use a yt prestige pro ig. This was strung at 56lb. I was absolutely loving the string and the tension. The grab on the ball, feel and power were phenomenal. This was better than expected for a $9 string! I am a string breaker, but can usually go 8-10 hours on a string like this, and the main breaks somewhere around the middle. I broke this top main in the grommet on an overhead miss-hit. The ball had to hit dead on the two strings at the top of the frame. This was after 1 hour of playing with this string. Was this a stringing error, an issue with the string, the grommet or simply the miss-hit? I strung it myself on a kipper that I've had for 15 years. I've probably strung upwards of 300 times as I strung for my high school team 15 years ago. Realistically, the drop weight or clamps wouldn't have touched where this broke. Thoughts?
