Freestyle and snap start help

I’ve been yoyoing for a couple of months so I can do a few tricks and I was wondering if you guys could give me a few tips for freestyle yoyoing just in case I decide to enter a contest. Also i need help with snap starting yoyos because when i do this my yoyo starts wobbling in every direction. thanks ??? ??? ;D ;D ??? ??? ;D ;D :-\ :-\

for the freestyle just practice shake up your tricks learn more and be realatively good at the style you compete in, for snap start I can’t do the right hand one but I can do my off-hand one but it just takes practice.
