Best Dragooon combos

I wanted to start my own thread because first of all I love talking about Beyblades and to get the opinions of others. Now i know i have posted these combos up on other treads (MSF-H Killerken Dragooon FGrin or BGrin) thanx to the members for answering my questions about these combos but lets really get to the meat of this topic. Now there are many diffrent Dragooon combos out there but which combo is well-rounded/best if there is a combo. Feel free to share your best Dragooon combo, and if you have an opinion about the combo I list off im all ears.
I wonder what dragooon killerken/balro SA165MF will be like?
This doesn't really need a thread IMO.
