Hi All, I have just started stringing my own rackets with a Pros Pro Shuttle Express and notice the strings a getting littles cuts\nipping causing the string to break after a couple of games. I have had a couple of string break during the stringing process causing me to open a new pack of string to replace the broken one. Does anyone know how i can fix this issue? Is the gripper gripping to tight causing the cuts in the string when pulling? Please help, i feel like i'm wasting my strings. I have attached some image of what i mean.
