General Tennis Racket Questions?

I recommend the 3rd one first and the 2nd one next. My reason being that they are generally light, which allows for a swifter, easier swing. They are also recommended for players from 2.0-4.5 and 3.0-4.5. I prefer light rackets, because i am able to swing easier in situations where time is of the essence. The weight is a big factor in rackets. I don't know what is considered heavy other than over-sized rackets. The are much slower to swing and limit the power you can generate while hitting a serve to a ground-stroke to a volley.
