First of all, I enjoy reading the 1H vs 2H threads. This is not a knock against one or a praise for the other as I belong to neither group. One undeniable fact is that there are more players (that grew up in the "graphite" generation - aka since the POG) use the 2hbh than the 1hbh. 1) This has to due with the evolution of the racket. With stability, forgiveness, flexibility and lesser weight of the modern racket, the TYPICAL players and weekend warriors can now generate higher racket head speed. Greater head speed results in more power, thus more topspin is needed to keep the ball in the court. 2) The grips are getting more and more extreme (eastern -> semi -> western). This all leads to more and more topspin. 3) The modern strings are more spin friendly. Sampras commented on Luxilon a while back. 4) The improvement of the strokes (the modern forehand, etc.). Another thing to consider is the mechanics of the topspin backhand. The 1HBH's point-of-contact is further in front of the body and its striking zone is LOWER than that of the 2HBH. Back in the wooden days, when most TYPICAL players slice and dice with the continental/eastern grip, the ball bounced much lower, thus making the 1HBH more suitable then. Now, it's just the opposite. Nowadays, you have balls coming at you with greater velocity, thus giving you lesser reaction time. This makes it harder to contact the ball further out in front of your body which is required by the 1HBH. With the 2HBH, you can hit the ball a little bit later. In addition, because the balls that come at you have greater topspin, they will bounce higher. When they bounce at chest level, it's way above the striking zone of the 1HBH, but not so in the 2HBH. IMHO, the 2HBH popularity came about due to the evolution of the game. This doesn't mean that an elite player with a 1HBH couldn't do well. Again, I'm not talking about the elite players who have the athletic skills to dominate regardless of backhand techniques. I'm talking about the 95% of tennis playing public (aka us). With today's FASTER AND HIGHER bouncing balls to the backhand side, it's just easier for a TYPICAL player or weekend warrior lacking the athletic skills to handle them using a 2HBH. Your thoughts?
