So I just started playing tennis a few months ago. I bought this used racket, and it seemed like it had different strings from the stock which was fine. But after a little while one of the strings broke and I was wondering for string recommendations for a relatively new player.

Another thing I was wondering was what is the difference between a Yonex V Core 100 and 98, and is this an alright beginner racquet?
