there are many kinds of beys like attack,defense,stamina,balance..
my opinion on beys will be:-.
storm Capricorn- i think this bey is good because of its bouncy sp…in track.if it bounces and hits towards the end of the energy ring,it can cause great damage.its tip makes it almost impossible to predict where will it land..
dark Bull- its horns give a great smash attack causing great damage.its tip is very good .it is almost an attack tip.if you lunch it at a tilted angle,it will revolve in a flower shape causing it to move everywhere in a stadium..
rock Aries- its spin track is made in such a way that it cancel attacks hit on its spin track.its tip is good in defense keeping it in the area where attack & stamina reach in a weakened status giving it an advantage..
flame Saggitario- its spin track have a great strike attack.its tip gives great stamina that helps maintaining balance,giving it an advantage towards beys.
