My friend wants a cheap and well balenced black knight racquet, he wants a racquet with: somewhat good strings, he doesnt care about the grip and he wants it to be light weight. and tell the cost thanks
Well, apologies but you're just going to have to tell him that it isn't possible to get a decent BK racket (or a decent racket full stop) for $20-$30. $60 would get a decent enough racket whereas it is unlikely that $20-$30 would get anything anywhere near decent - he's just gonna be disappointed.
