Hi guys. I have a little bit of an issue with my stringing. There seems to be a repeated level of wear / stripping of the strings (BG80) right in the centre section of my string bed. This seems like stripping of the outer jacket of the string and happens within a month of the racket being strung. I personally break my strings well before this oblivious stripping occurs. Is this due to my stringing technique? The centre stings are never clamped and go through the easy single grommet holes, so I am a little unsure of why this is happening. Any suggestions would be great.
