Armortec 900 Technique

4Us in general is more fragile than the 3U. In the case of the AT900, 3U is the popular weight version (I have 3UG5 JP).

 

All else being equal:

Heavier frame = more material (or denser) = greater structural strength.

 

What is your grip size?

 

I am assuming you purchased this from an authorized dealer, which would be CD coded. In this case, the AT900s, G4 and G5 only comes in 4U while 3U only comes in G3.

 

I broke a 4U before too..And yes you are rite about the density of the materials to the frame..

I have friend that are using 4U and it is fine, However they take extra caution.

 

i own one technique 3ug5 and tried friend's power 4ug4
totally different feeling, is this the same between 3ug5 technique and 4ug5 technique?

 

No because they are two different weights. Also, with less material inside the racket on the 4U, the more flexable and fragile the racket would be.

 

3U is a lil heavier than 4U,
3U is able to generate more power since it is heavier but not so good for defence.
4U is lighter & has easy to swing, but not as strong as 3U.

 

Both 3U and 4U have very different feeling...

3U is not as fast as 4U but with the right technique you can defend a 3U like a 4U..

Just like me I tend to over swing with my strokes therefore a heavier racket will give me the accuracy that I need.It is imperative that you know your stroke well.Just like my friend he cant play a 3U as his stroke is much slower.Therefore, he he needs a racket that gives his access to a faster swing.

I very much agree that 4U is not as durable as 3U.That what i feel so it is your call in what you want..

In terms of power, it depends on your fitness and stroke.Of course the 3U is more powerful but if you are able to swing fast the 4U would be good too.

 

I think 3U actually comes in all 3 grip sizes... it's that way for every other racquet, so I'm assuming this is true for the AT900T.

 

yes, it may come in all 3 gripsizes (maybe even all 5)..but it's up to the distributor to decide whicht hey're going to import.

In Holland, for example, 4U's are very rare. 4UG3 almost impossible

 

Unforunately it does not. Yonex Canada officially brings in 4UG4 and 5, and 3UG3. Yonex USA officially only brings in Yonex 4UG4.

However at the local store I shopped at, they have managed to obtain a few 3UG4 on occasion by talking with Yonex Canada.

 

Then I'm lucky though; the store I purchase racquets from gets CD versions in many grip sizes for 3U. For AT, I got 3UG5, and 3UG4. I guess I'm lucky

 

Are you sure it is the 900?

What is the date codes you have on those and show us some pics too.

 

I saw some G4s in 3U for sure at my proshop. I didn't purchase though (I got an AT700). As for the 3UG3, I saw an AT700 with it. Sorry for mixing it all up;I thought this problem occurred with all of the ATs. My mistake.
