Pretend you are at a tournament and you've broken the strings on all the rackets you brought with you. The only options from there on are to borrow a racket or forfeit the match. To further make life difficult, no one plays with the same racket you play with. You also play with poly. (EDIT) Grip size will be the same for your racket and the racket you borrow. So unwilling to forfeit, you now have two choices: 1) Racket #1:Similarly spec'd (same head size and similar flex) to what you play with, but the tension is noticably looser by 4-5 lbs and a different type of string (gut). 2) Racket #2:Smaller head size and stiffer, but relatively the same tension and string type (poly). Which racket would you choose? Are the strings and tension more important than the frame? Or vice versa? Reasons?
