Brand New Blader, Good Combo?

I'm relatively new to the world of Beyblade, only starting last year. I've become quite good, even though I have a small collection of the Metal Fight beys. I just recently began battling competitively, and I wanted to know: Is this combo good?

Of course, Libra is like the coolest ever, so I won't be changing that. But I will definately listen to your suggestions! Libruhhh

Face: Plastic. Doesn't really matter what's on it.
Energy Ring: Libra
Fusion Wheel: Basalt (I'm ordering Diablo Nemesis, so this might change.)
Spin Track: Switching off between T125, D125, and WA130.
Performance Tip: WD.

I'm aiming for Defensive, able to withstand strong attacks, but I also like to smash the opponent as well. I just don't know, so please, post your suggestions!
This belongs in build me a combo #2. And Basalt BD145 Variants work better then D125.
