Hello,
I don’t no if it’s me or the yoyo, but when I’m trying to do a brain twister or a barrel roll (yomega tricks) I feel that the yoyo is losing speed.
Conclusion: my yoyo stop’s turning before I get it back in my hand.
I’m using a Fireball (yomega)
Thanks 
Well you could try a more butterfly shaped yoyo like a Dash or Maverick from yomega if you wanted to stay with the company. But yes it is the yoyo.
Shame on you Fireball.
It is because the fireball uses a transaxle instead of a bearing. That being said, it is still possible to do those tricks with a Fireball despite its shape, it just takes more practice.
I bought several cheap yoyo’s that were that shape, and the only one that sucked was the fireball. That transaxle is so slow.
Its because the fireball is a transaxle… Get a ball bearing yoyo that’s butterfly shaped and you should be fine. Get the YYF ONE, its cheaper than the fireball and is SOOO much better for 1a… You can keep the fireball for 2a though
You could always buy a Duncan metal drifter and use sili stickers(since it a pain to keep buying friction stickers) and clean the bearing.
