Is 'unlock unicorn nine unite' a good combo?

Hi, my name is GJ and I have unlock unicorn Down needle which is my only beyblade . I am thinking of buying S2 and lost Longinus for making a good combo for the U2 layer. I chose the nine disk because the layer has 9 blades on the outer rim and I chose unite to go a bit old school with Ray unicorn. Can you guys test it against competitively good Dual layer combos like K2 spread Revolve and tell me how it's performing?
