Good Value for Your Dollar
This book includes various black&white action photos - critical static positions - captured from dynamic motion. The text in the book is not overly verbose. It gets to the point and supports the critical positions the author is trying to convey.
The techniques described are from the Pete Sampras/Agassi era - still valid today but certainly quite not what the current top players are doing today - ie; Federer, Nadal, Safin, etc. - just in case you are trying to hit the ball like Roger or Rafi :-)
While there is good material here to help all levels of players on sound tennis fundamentals, the information given does not cover finer nuances of stroke production.
