Well, At 19 and playing frequently, you could handle the Adidas Metalbone W Team, but it may be on the stiff side. For your age and skill level, I'd likely recommend something a bit more forgiving and maneuverable, like the Wilson Bela or Bullitt Cortador.
Both are lighter around 340-350g and have softer compounds to reduce arm fatigue. But if you like the controlled feel and can swing the Metalbone well, it could work too.
