I am playing with gut, so if I look at the fraying of the gut after playing a couple of weeks, I see the following pattern: As you can see, I consistenly hit above the sweet spot of my racquet. I do notice this when hitting, most of the time I know that I am not on which result in more frame vibration and a hit that does not feel clean. It is not racquet dependent, I seem to be doing this with all racquets. I also put in a lot of effort to look at the ball until it leaves the stringbed. Do you think this is something I need to solve by changing some stroke mechanics or footwork? Is there something wrong with my hand-eye coordination or isn't it unusual to hit high in the string bed consistenly? I can't recall the last time I hit too low. If I frame a shot, it always is at the top. The racquets I have (PK 5Gs and Volkl C10 Pros) are all 27". Could my problem be solved simply by using a stretch racquet instead of a normal length one? There is also a possible solution to add lead tape, but I really would prefer not to make my racquets head-heavier. I also wonder what amount of lead tape you have to add to raise the sweetspot about an inch. All help is very welcome as I really don't have a clue how to solve this problem. If my stringbed was also frayed in the middle and a bit below the middle, than it clearly is my unability to hit the same spot each time. However the stringbed is only frayed as being displayed on the picture I posted.
