...did not believe me when I said I needed to restring my racquet yesterday. I used ALU Power at 55 and Sensation at 52. I've had this setup for over a month. It had lost a ton of tension by yesterday. He didn't believe that a person my age and at my level (14 year old playing for two years; coach says I'm really good for only have played for 2 years, like I play with seniors and juniors on the varsity team at my coach's). He got mad because he didn't want to spend too much money on tennis. Then I showed him Jolly's guide to strings, and POOF! change of opinion! I'm ordering Blue Gear 17 to put in a full set at 55 lbs. in my Microgel Radical Mid+. Wise choice?
