Umm... singles... well, both are good, but AT700 might be better for a smasher, and AT900T might be better for you if you prefer netplay, defense, drives, etc. I use an AT700 and use it for netplay, and not smashes, so it doesn't really matter. They're both great racquets anyways.
AT900-t feel more hollow because it is more head light vs AT700. You have the answer yourself. You just need to ask and anser them. 1) which one fit your style better? 2) which one produce the shot you want? 3) which one win more game for you 4) use the force...
will the grip size affect the performance of a person? and is the at500 more durable if it's 3U than 4U?
grip size does affect performance, as u can switch to back & forehand easier can increase speed of ur game. 3u is definately more durable than 4u. at700>at900t =]] 900 is too stiff.
hmm ok some people find the 900 too stiff and some find it flexy... To me it is just rite the at 700 is very stiff..
Initially when I used my 900T, I had the impression it was too stiff until I used it for a while and got used to it as I adapted. Workds great!
It definately can holds up to 30Lbs. I have mine strung at 30 to 31lbs. So far i have not broke mine. But i do have friends who broke their AT900 at 28lbs,25lbs and even 23lbs!
I guess it depends on the person..but ants its right that it can hold up to 31lbs or more. so depends on what you feel comfortable with and willing to take the risk..
Yeah.. i always use 3U. The only 4U that i had which was given to me.. i didnt even use it for gameplay. But i let my bro use it instead. hehehe
