Is there such a thing as a specialist serving coach? I'd really like to see one brought in to either strengthen some of the GB women's serving (e.g. Katy) while improving the consistency of others' serving e.g. Laura and Tara whose serves seem to break down under pressure. It's just that it doesn't seem like a strength in the GB women's game and is such a technical issue, that specific help might be useful. Or is it just a very difficult part of the game to improve, once you've reached a certain point in your career?
