I tried a very nice modification so if you are interested you can also try it, and I promise, it works perfectly:
You need the Arc Bahamut layer and Ring, the disk u know. The only driver that will work is Defense, because you need to add a very special part: This modification is only for people who dont mind to destroy a tornado beyblade if they have one but never use it. That's why I Crashed my Tornado Earth Eagel to get the Metal Ring. This Ring is able to be carried by the defense driver, also there is still enough capacity to put the Ring disc on it. At last you just need to fix it by completing with the Layer on top and that's what I call : Arc Bahamut Ring Eclipse defense.
Remember: You can actually use every metal Ring but it has to be from a Tornado Bey
I will devour your souls... I'm your worst nightmare... I'm NIGHTMARE LONGINUS! GO SHOOOOT!
