I recently came across the Sergetti stringing method and thought I'll give it a go. I am amazed at what a difference it has made to my game and I'm curious if others here have had a similar experience? Up until a month ago, I had never even heard of it so I am hoping that it may be able to help others here. It's a scientifically developed proportional stringing method that claims to greatly increase the sweet spot, increase the life of the string bed among other things. I'm a sceptic by nature, but I can certainly testify for the increased sweet spot and here's why: I play in a doubles social comp and I recently played the best match of my life using this stringing method. I was able to beat players that consistently beat me. I served 3 aces in one game (2 against our best player) and my groundstrokes were better than ever. Between games, I noticed red marks all over my new white poly strings. My coach uses new tennis balls and marks them with a Red X (he reuses these later for coaching). I had red dots spread out all over the place- I had not been hitting the ball that well after all - but the shots felt great and came off the racket nicely. It had to be the larger sweet spot from the Sergetti stringing. I also get tennis elbow. Next day - no tennis elbow for the 1st time in months...same strings! Played my second game this week - played well again and no tennis elbow. I can't comment on the enhanced string life because I haven't played long enough but I can say without a shadow of a doubt that the sweet spot is much bigger, it's improved my game out of sight and I don't feel anywhere near the shock from off-centre hits. I hope that this helps others and I am interested in any feedback from people who are using this or other similar techniques.
