Midplus
The midplus tennis racquet is a compromise - more powerful than the midsize tennis racquet but not as powerful as the oversized. These tennis racquets are becoming more popular than midsize racquets.
How has racquet weight changed?
Tennis racquet technology has changed dramatically in the last 15-20 years. From the venerable Jack Kramer "woody", of the 50's, and 60's, to the T 2000 steel frame of the 70's, we now have space age technology in tennis frames. Graphite and fiberglass, used by NASA to build the Space Shuttle, have replaced many of the Kevlar frames of the 80's. They make the tennis racquets lighter and more powerful. It is one of the reasons that the game has become so fast recently. When shopping, look to the top brands like Wilson, Prince and Head tennis racquets that would utilize this tennis technology.
Larger Frames
A larger tennis racquet frame like you'd find on some Prince racquets generate more power. A larger frame is more resistant to twisting. A larger frame has a larger sweetspot. Larger frames break strings sooner due to the string lengths.
Head balance
Head light tennis rackets are better for serve and volleyers who need to move the tennis racket quickly. A head heavy racket is a little better for baseliners who want to place more mass behind the racquet. Most tennis rackets are only marginally head heavy or head light.
Does size matter?
Generally, advanced players prefer a smaller tennis racquet head size, from 85-95". Since most advanced players have a longer and faster swing, a smaller head size helps control the ball. Conversely, beginners and some intermediates tend to prefer a larger head size, which gives them a bigger sweet spot, and is generally more forgiving when mishits occur. No matter which size you choose, be sure to demo the racquet first before you make a buying decision.
Longer Frames
Longer tennis racket frames have higher swing weight than the same frames that are shorter hence the longer tennis racket frames are less maneuverable. Longer frames generate more power than the same frame that is shorter.
Extra Long Rackets
The new longer tennis rackets are typically about 28 inches long. Given that most tennis racket manufacturers like Prince Tennis Racquets, now produce a longer racket, it's safe to say that this idea does work. It seems to help add a little power to the serve. The only tricky part is making sure that you can still hit the same kind of stroke with the longer rackets that you can with a normal racket.
Super-oversized
Some companies, like Wilson rackets, have introduced super-oversized tennis racket models, which are a bit larger than oversize (typically about 116-120 sq. in.). There are even a few models around 130 sq. inches, which are probably much too big for reasonable play and should be avoided.
Head Length
Take a tennis racquet and find the length half way. A tennis racquet is typically 27 inches long so this is 13 1/2 inches. If the racquet balances halfway, then it is even balance. If it tilts to the racquet head, it is head heavy. If it tilts toward the handle, it is head light. The balance of a racquet can make two racquets of equal weight feel different.
What is a Performance Racquet
There is a dizzying array of help for performance racquets today like Wilson, Head and Prince tennis racquets. These racquets are unstrung, and are generally quite a bit more expensive than pre-strung racquets. But, there is also a world of difference in material, weight, feel and overall performance between the two types of racquets. Go to a qualified tennis professional, and they can assist you in selecting the correct frame for your playing style.
Racket Rattles
A rattle in your tennis racket may be caused by some loose graphite, this is not normally a cause for concern. Check the butt cap for a trap door. Remove the trap door, using a small-pointed hard object, and tap lightly on a hard surface to release the loose graphite. Watch for this problem when buying a used tennis racquet.
Head Size
Larger headsize of tennis rackets (like you'd find with some Wilson Tennis Rackets) gives you power, smaller headsize gives you control. For those of you looking strictly for power, the head size should be between 107Ħħ and 125Ħħ. If you want a mixture of power and control, the head size should be between 100Ħħ and 105Ħħ. And for control freaks, the head size should be between 85Ħħ and 98Ħħ.
Heavy Frame Advantages
A heavier tennis racket frame generates more power. A heavier frame also vibrates less and has a larger sweetspot. Your local pro-shop should have a variety of frames on display for you to try. Quality brands like Wilson are your best bet.
Racket Storage
Off court, a cover or racquet bag will help protect the racket. Store racket in a cool, dry place, away from direct sunlight. Excessive heat, cold, or moisture can damage your tennis racquet and strings, and sunlight may fade the racket cover. When purchasing a racket try to make sure it comes with a cover especially if you are buying used tennis racquets.
Weight
Tennis Racquets right now weigh about 11 and 1/2 ounces and decreasing with time. Some racquets are even less than 10 ounces. The lighter a tennis racquet, the easier it is to swing. However, light racquets place less weight behind the shot, and hence you have to swing faster to get a more powerful shot.
