I own a Silent Partner Jazz stringing machine, and i string my racquets at 60. recently, during a tourney, i had to get one of my racquets strung at a pro shop, and they strung it at 60 on a babolat star 5 machine, and it seemed A LOT tighter than my machine. so to make a long story short, i loved the tightness of it, so if i want to achieve this same tension on my silent partner jazz, what tension should i string my racquets at?
