Use of Grand Ketos Parts in Combos?

Hey,

I don't have many beyblades at this point in time, but one of the few I do own is Grand Ketos. I'm looking for any good combos so I know which other blades to buy in the future. Do you have any suggestions?
That would belong in the Purchase Consultation topic, not here.


Also, will you be able to conduct tests with Grand for us ?
