??? I keep buying yoyo’s but, none of them have the long spin times and speed that i want i cant finish any master section tricks without my yoyo dying. Whats a really fast long sleeping yoyo by yoyojam
well what yoyos do you have?
PHENOMIZM!
I have a dark magic, fiesta, sfx, and my phenomizm is coming in tommorow
Try working on throwing harder, the yoyos you have are just fine. 
Before you work on throwing harder, work on throwing straighter.
The yoyos you have are capable of most any trick.
The yoyo is slowing down because the string is rubbing on the body.
yea pretty much but, have you tried the dark magic 2?
i throw very hard and strait
Then I see no reason that your yoyos should not spin long enough to do most any trick.
Wise man say “Seek first to blame yourself before you blame your tools”
it is probably you
but if not, make sure you have the speed bearing and not the thin bearing in the yoyo.
Then throw harder and straighter. Those yoyo you have is fine enough.
practice my friend, i know you havent done your best yet.
and. . .
This is a very wise saying.
Is it too obvious to ask about string choice? Some type 6 polyester will provide the least resistance to the spinning yoyo.
THROW AND CLEAN BEARING.
also a phenomizm needs to b lubed cuz its responsive.
work on your throws. all the yoyos you have a capapble of doing the hardest tricks in the world!
Hiroyuki Suzuki won world champions with it!!! Phenomizm!!
PHENOMIZM: CAPABLE OF DOING ANY TRICK IN THE WORLD.
SFX: CAPABLE OF DOING ANY TRICK IN THE WORLD.
DarkMagic(2): CAPABLE OF DOING ANY TRICK IN THE WORLD.
sO BASICALLY YOU have more than enough to accomplish world championships.
