[Takara Tomy]  Old cho-zs vs new cho-zs

Hey everyone, i watched a lot of videos about battles between the "old" cho-z beys (metal on the layers) and the new ones (made of plastic and much thicker to fill the lack of metal, now almost disappeared from these layers). There's not a supremacy, every battle is pretty unpredictable. So, i would like you guys to post the best combos from both types. 
This would be helpful for many other bladers too Grin
It would be best to subscribe to this thread for your question, as this deals with the competitive listing of Takara Tomy Beys even until now (I think):
