Hello, i'm planning to get either the Iso Ti SX or the MP 88.

I already have a Ti-10 2U G5. But i'm looking for a racket which has similar attacking qualities, but with greater maneuverability/defensive capabilities than my Ti-10. I was thinking that a 3U racket would be able to help in this area.

Thus, i want a light, but head heavy racket such as the iso Ti SX or MP 88...
which do you's think suits wat i'm looking for best? which is better in offense? which is better in defense? which has better control? are both rackets 'slim' ? which is head heavier? which is more aerodynamic?

thanks.....
