It seems like none of you guys have watched tape of the old masters recently. In track and field, the sprint times have gone down radically over time, due to the ante being raised. It's like saying Jesse Owens was the best sprinter ever. He would find it hard to win a college race now. It's far worse in tennis. Laver in his prime would be destroyed by any of the top guys. Just look at the tapes and see how slow the shots are, how little action is on the ball, how bad the footwork is, how antiquated the equipment. What if they were playing with the current equip? What if, blah, blah. They would still be destroyed, due to bad techniques.
Kuerten had a devastating bh.
Gasquet
Almagro
Sampras: only against Agassi. Sucked against most others.
Henin: hon. best female bh ever.
Yet, all of those guys always ran around their bh given the chance. The ih bh is a dying shot. Takes much longer to perfect, given the deltoids are the driving force, and hip timing/tech. is harder to master. More versatile, better for volleying, and chips, and oh, and more reach.
