Is Sting Unicorn 9-60 Ball a good Stamina combo?

I recently looked at tournament winning beys and saw Gale Wyvern 9-60 ball but found it to be too light so I switched it for Sting Unicorn and came out winning against a competitive Silver wolf combo and lots of other competitive beys but these battles were between me and my brother so I don't know if I got lucky or not. And currently I'm in math class right now so I don't remember all my parts but I should remember most of them

UX-Buster Dran
UX-Golem Rock
UX-Draciel Shield

I'm giving this list In case anyone knows a great competitive Stamina type :>
Sting Unicorn 9-60B is a good stamina combo, although the better version would be Sting Unicorn 9-60O. The latter has the distinction of being the winning combination in a Hasbro tournament held in Spain; the Beyblade YouTuber ZEEBEE (Zeonic Blader) mentions it a number of times in his competitive videos and tests other combinations against it as well.
leonclaw 5-60 orb if you don't have orb you can use ball. all orb is a stronger ball tip like its more beefy. it has a little bit more stamina then normal ball

omg wrong tab

omg I'm wrong

this is the worst fumble I ever had
Focus on the math class



The combo is fine. Sting Unicorn is one of the stronger Stamina types besides SilverWolf and WizardRod.
Focus on math, but US 9-60 O is like the 3rd best stamina combo, behind rod and wolf ball/free ball, a great Phoenix counter too
