<html>precisely, I think I will pick between Isometric 900 SS or Carlton Aerogear 2000 TFX, actually I try the carlton one last nite, the only info I know is it is Titanium, so I hope is the Aerogear 2000 TFX, there are tons of power when smashing, and how, I tried the Isometric 900 SS the week before, and I love it too, even though it is harder to smash with SS than SR, but I find more power in smashing when using SS, for SR <br>very easy to get ready to smash but not enough power. Experts in picking and comparing these rackets, please give me a hand, this is urgent, thanx a lot guys!! </html>
