The Yonex Amortec(head heavy)Series are now being replaced gradually by the newer Voltric Series. The Nanospeed headlight series are being replaced by the newer and lighter but stronger Nanoray series. Please refer to the new Yonex Nanoray catalogue.According to most reviewers Nanoray racquets are mainly newer versions of Nanospeed racquets which will probably be withdrawn eventually.
There are explanations a plenty on the web on the technical aspects of racquet performance.To me racquets with high repulsion are very powerful with a lot of "whip" .Very suitable for doubles play and people who need the racquet to assist them in adding power to their strokes. High repulsion to me results in less control of shots but that can be adjusted by higher stringing tension and technique.A high repulsion racquet like the Nanoray 80 or defunct Nanospeed 990 with a very stiff shaft however plays like a wooden racquet,powerful but difficult to manouevre and much slower in defending.Repulsion racquets with a more flexible shaft and heavier head can do better in drives and defence Egs. are the Nanospeed 9900 and even the cheap Taiwan made Nanospeed 800 still available in KL.Head heavy racquets of course are built for hitting powerful smashes but may be a bit slow in defence and have less control.At the other end of the spectrum are hold racquets which have less whip but allow more control and accuracy and are probably more suitable for stronger players especially pros with very strong wrists.Examples are the Amortec racquets.
Racquet charts aside,before you think of getting rid of that expensive racquet especially the balanced racquet,just like cars for example, many experienced players particularly those from sophisticated and innovative societies know that racquets can be modified slightly to make them more playable to suit the player :If you have difficulty in controlling placements it may be because the grip is too small, all that needs to be done is to pad the grip with more cellophane and wrap a thicker grip to increase the diameter .If the grip is too large, the wood can be sand-papered down.The new grip to be applied can be a thin grip.If the racquet feels too head heavy it can be balanced by making the grip heavier by thickening or padding it. Conversely if the head is too light it is possible to add a lead tape to the head to make it slightly heavier.If the racquet frame feels too hard and stiff, the string tension can be lowered. An extra long racquet can be made more playable in doubles by for example gripping it a little higher when executing drives.However a racquet with a stiff shaft cannot be made flexible and vice versa.Stiff racquets are generally more suitable for strong and expert players especially in singles.A player who cannot analyse how and why equipment can assist or impede his /her play is probably a player who cannot analyse a game and its tactics as well as the physical and mental demands(such as concentration)and also unable to deduce why they won or lost a game.Then they do absurd things like blaming the coach for example,amongst others.
