Hi, The guy who does the stringing of my racket is unable to string the topmost cross string till the hole where Yonex original strings are. He does it till one hole lower. The reason is that the clamp he uses to hold on to the strings is not small enough to go into the small space left between the racket frame at the top and the topmost string. Please let me know if there is a way to get over this problem. Are there smaller sized clamps available? Is there a specific technique to string the topmost cross which this guy probably is not aware of?
