I just strung my new racket couple days ago. I tried higher tension and man it feels like i'm hitting with a board. Now i feel quite unhappy with it. I don't want to restring it as it will cost me money. I thought letting it sit down for a while will loosen the string sooner or later. My friend told me just hit with it as it will make the process faster. (hit with machine or just practice serving, the point is, use it) I also let it sit outside my tennis bag. I thought leaving it outside will help too (i don't know where i got this idea from i just think it will work) So any other suggestion? Thanks!
