Surprising discoveries/findings about underrated beyblades

What are some things you found out about beys that are underrated? 
One thing I found was that the Venom ring from gt has pretty good attack power
Cho-Z Valkyrie and Lord Spriggan only recently kind of fell out of viability within me and my cousin's bey club. So that's interesting. It's not like we had bad combos either, those layers just held up surprisingly well.
Burn can pack a hard hit against some sparking things
Reboot’ is really good in the standard stadium with guilty. Maybe everyone else already knew that but I had to try it after the recent tournament report and I have a new favorite non rubber attack driver.
