Wow!! At 2 points as well! How did you do this one then? Edit - ahhhh - just saw the other thread - it was the same one as the hairline crack guessing game one. Take it it's another shuttle smash mishit then.
isometric for me xD once i start using it, i cant stop. and my oval carbonex has been ostracized for years. >_>! it's like a backup for friends who forgot to bring their racquets
I found a broken Nanospeed 9000X, exactly like yours in a trash can. The frame broke at the same places, around the 2 O'clock and 4 O'clock position. Are those parts the weak points of Nanospeed 9000's ?
Oval frame has a better sweeter feeling when I hit with it. By the same token, off-center shot are amplified in vibration and loss of power. I bought my ISO mp21 thinking that it will be easier to play with. It is easier in that it is off-center-shots-friendly. But lacking much power and feel when it comes to shots that are hit right. I learned badminton with oval frames and so bought the 30ms for a try. Switching from ISO back to Oval was not a big deal nor an adjustment. But I get to hit better (90% shot in the center) and feel better. 2 minutes adjustment back to oval frames. Both rackets strung with BG80 at 25Lb. Frame size is very similar but the hitting area (sweet spot) is different in size and feel significantly. But note that flex is flexible for mp21 and stiff for carbonex 30ms. Not sure if it contributes to the difference in feel, speed, & power given the same string & tension. My preference : Carbonex 30ms. Iso mp21 over carbonex 30ms oval carbonex 30ms over iso mp21
Just curious, but what type is this? http://www.sweatbandbadminton.co.uk/shop/detail.asp?ProductGroupID=15185&c=1744&d=413
Tough to make such a large generalization. There are great rackets to be found with both oval and isometric heads.
Oval racquets have two great advantages over iso. One is much better maneuverability and the other is more uniform natural flex of the frame. The former moves the racquet around through the air faster. The latter gives you a more punchy shot, unlike say the iso NS 9000 X that gives you a somewhat time-delayed kick power.
Oval shape is more streamline, iso more squarish. Oval has smaller stringbed and hence less string resistance in addition to the reduced resistance from its shape vis-avis iso. The oval shape can be pressed or compressed inwards for it to spring back (regain) its original shape more uniformly. With high tension strings a hit on the springbed "compresses" the oval frame which then regains its shape to give the shuttle with that unique oval punchiness. The iso shape "kills" the flex that the oval has. The NS9000X or some iso racquets that have elastin try to copy that oval flex, but poorly.
True, an iso has a bigger stringbed and therefore has a bigger "sweetspot". But what about the quality of its sweetspot? Air resistance or its lack of it is very important. You can test this yourself with two identical racquets, except one is with string and the other without, by swinging them. Notice the dramatic difference in speed and maneuverability between the two?
i grew up using oval rackets, from Blacken SP, to Carbonex 8,9s, then to Boron 200, Aerotus 110SP. should be experienced enough to tell the difference. but Iso rackets just make hitting the shuttle easier and more forgiving. also, now i believe with the newer technology, i can swing all my Iso rackets faster, crisper than my old ovals. hence, my conclusion that Iso is better for me.
WOW, these are some theories. So, may I assume the box frame of Cab30ms has less air resistance than the aero frame of AT900t? Also, my source told me that Yonex tennis frame with 95 sq in (ISO frame) has bigger sweet spot than other brand oval frame with 100 sq in. Hummm? Let's see, a racquet without string weight 87g. vs same racquet with string weight 91g, I think the racquet with string will feel head heavier and harder to swing.
Weight is just one of many factors impacting on maneuverability. Others are length, presence of "T" joint (yes, "T" joint makes a racquet more ponderous, which even Yonex admits), cross-section of frame, stringbed area, frame shape, balance, thickness of string used (thinner strings have less air resistance). Also many modern ovals are not box shape. In fact some have very thin cross-section.
