Question 1. What is the difference/advantages of stringing the mains tighter/looser than the crosses? Question 2. I currently have the Head youtek IG instinct and the shape of my racket looks pretty odd compared to the other instincts. What i mean about that is the top of my racket is pointy(not to pointy but it should be more rounded) its not the racket thats making this happen its stringing cause i believe i strung it a little too tight. If i string the mains tighter will it become more rounded on the top of the head or more pointier? Or do i have to string the cross tighter? Heres a picture of the racket. its not mine but im just showing you guys so you know how it looks Please answer both thank you!
