The Head Vilas (I own 5 of them
) is a regular sized (mini for you younger members of the boards) racket that is of wooden construction. Like the PF Flyers (sneakers for you younger members of the boards) it contains a wedge too. This wedge does not guarantee that you can run faster and jump higher, but it does add weight to the head. There is a graphite or fibreglass wedge in the head of the Vilas. Also, down the shaft of the Vilas are graphite laminations that make it stiffer. Of course, stiffer is relative as anyone over 40 can tell you. Stiffer by wooden racket standards is more than flexible by today's standards. For the six months a summer ago that I played with the Vilas, I can veify that you can punish the ball with wood. The biggest differences for me are second serve and volleys. You must be precise.
I find that topspin is easier to generate off the forehand with wood, but harder off the backhand. When I was coming up, my second
real racket was a Spalding Pancho Gonzalez. I remember the older guys at the club saying I had a nice backhand. I did because I am left-handed and the natural crosscourt shot from a right-hander is to my backhad, so it was either get a backhand or go back to golf. Anyhow, they were all really impressed when I started hitting topspin backhands, which coincided with my acquisition of a Slazenger Challenge 1, probably the sweetest wooden racket I played with in my misspent youth.
Back on subject. The pros could hit serves as hard with wood as they can today. The big difference again was the second serve. You'd better reign in your first serve because hitting a kick serve with a wood racket can be challenging simply because of the size of the head. Also, not necessarily the weight of wood as much as the balance kept players from using really extreme grips like they do now. The Eastern grips and the Continental were the primary grips because you didn't have to move your hand much. Even Borg, who hit with extreme top hit with an Eastern on the backhand.
Rod Laver is widely regarded as the first player to really come over the all
on both sides. His topspin backhand was one of the fiercest shots on tour when he was in his prime and Ken Rosewall's elegant sliced backhand was the perfect foil to Laver's slashing and attacking. Ilie Nastase was one of the first players to hit a topspin lob off of a backhand, and did so on the dead run with amazing regularity. Nastase was also one of the first guys to really start making it up as he went. Nastase would play any shot from any position on the court. He did so either to win the point, or try and run his opponent.
I agree that prior to Borg, topspin on the backhand was the exception and not the rule. If you look at Borg early in his career, he played sliced one-handed backhands. It wasn't until he developed physically and became stronger that he began to consistently hit the two-handed topspin backhand for which he is now famous. McEnroe, while fully capable of hitting topspin, was widely renouned for never hitting the same spin twice in a row. He did this to keep his opponent off balance and probably more importantly because
he could. Arthur Ashe was also known for having a better backhand than forehand, and he could come over the ball as well.
Topspin backhands off wood were generally tighter in spin than they are today.
Mojo is dead on, it took really good technique and timing to hit a topspin backhand with a wood racket. But, when you hit the ball in the center of the, albeit small, head, nothing feels better than wood.
