Recommendation

NS9000S will be better.

 

It is not as heavy head as AT900P or AT900T, less stiff than 9000X which is extra stiff and demanding. Not sure about arc7 but ARC10 will be more suitable for single play. I do not know your current string tension/strength/preference but BG85 or NG98 at 25lbs or 24lbs for start should be fine.

 

If you are a doubles player, I suggest Arc 7 as the rest are pretty stiff. I have a friend who uses the NS9000S and he's having problem with his rotator cuff. Mind you, tension not really that high, probably 24lbs.

I loan him my Carlton 9500 Nanolite which is head heavy, 82gm and flexy with 28lbs tension and he love it ! After playing a few games with it, his shoulder is still ok and he asked me to sell it to him which I did (sob sob, it was one of my favourite racquet).

If you use stiff racquet and you don't have a strong arm or good technique, go easy on the tension, else you will be suffering from various problems.

 

I don't think there is a weight difference from the NS9KX its just the stiffness of the racket. Armortecs are more headheavy. A few of my friends own a Arc10 and when i tested it out is was pretty nice just needed time to adjust with it. I think you should try bg80 at around 22 or 23 at first. I don't think you should be going any higher than that assuming your mp22lt had factory strings? 22 - 23lbs is the way to go when you first start to increase your tension.

 

Also can try Victor nano5, medium flex, fast and probably cost half of the Yonex.

 

If drops and net play .. i agree with NS9000S .. If clearing and smashes pick arc 10..
Arc10 is good in continuos smashes.. Great racket for hard hitters.. Its UltraPEF attribute makes it possible to do continuos smashes without getting ur hand numb..

I do not know well bout NS9000S but i do own a NS9000X.. net play and drops are fast and accurate... smashes are very fast and accurate too.. but sound quality not so good and also my hand gets numb quickly after lots of smashes.. as u really need to generate a very fast swing to get a good smashes.. also if u r a beginner .. u might probably end up with the racket on u.. lol..
btw: got few friends who hit themself with the racket..

 

All your beginner friends have bruises on their left leg/knee ?

 

To stop clashes, you need to have a good understanding with your partner and also communicate more. Of course there will be cases where the clashes are inevitable but those can also be minimized, for example shots that are in the middle, normally those that return with forehand will take it.

Weird that you find Arc 7 difficult to use as it is probably closer in specs to your existing MP22Ltd than than the AT900T.

For tension, it really depends on your skill level and also the racquet, whether it is flexy or stiff. If racquet is stiff, using high tension can cause problem with arm, elbow (tennis elbow) and rotator cuff.

Personally, I use a slim overgrip on my racquet as I have small hands. I used to put thick replacement grip over the original grip but found out that it alters the balance point of the racquet though it does provide better shock absorption.

3U/4U is not grip size, that's the weight of the racquet, if you want more power, go for 3U. However, only the Armortec series are available in 3U/4U, most other yonex series are 3U/2U.

 

My first Arcsaber - a 3U G4 model, had a chip at the white part of the carbon nanotube - i did not do anything with it, just took it out and found it that way - fortunately i was able to replace it, but, for a 3U G5 model:crying:..
