New guy

I remember when I was younger and beyblade caught my interest. I had a couple beys but didn't really know much about customizing them or any of the new stuff, because I was too young. Saw them once again at Walmart recently and my interest has been rekindled. I miss the old school beys, and the engine gears. Can anyone recommend a well balanced but aggressive Bey? And what's the difference between most of the new and old beys?
I also enjoyed the engine gear beys when i was younger but the new ones are much more fun! with many, many, more customization abilities! Also where the old beys based everything off the attack ring and base, we now have many more control over our beys including hight, weight, radius, etc. Anyway some good agressive beys are,
Storm Pegasis 100HF
Lightning L-Drago CH120RF
Hell Kerbecs 85XF
Cyber Aquario W105R2F
Ray Capricorn WA130RF
Burn Cancer 90MF
