I have got two yo-yos

One yo-yo is a Duncan Butterfly from eBay.com yoyo-sam. And the second is metal non-brand. I learnt how to:

1. attach the string to the yo-yo
2. what for is the loop
3. gravity pull trick (how to hold and throw a yo-yo) - I can do that
   
4. sleeper trick - this sometimes I can do but still most of the time I cannot do
5. I did the gravity pull trick and sleeper trick with the one loop over yo-yo axis. First I listen to Yoyo-guy Dick Store to make yo-yo non sleeper, but then I realized that I need to do these tricks with gravity.
6. I discovered that the metal non-brand yo-yo has the wrong string - with the end cut - it should be a loop. So I learn to pay attention to the right string on the yo-yo.
   

I followed:

• Pre-school from the Yoyo-guy (Dick Store (?))
• gravity pull trick (how to hold and throw a yo-yo)
• sleeper trick
• Pre-school from the Yoyo-guy (too difficult for the beginner)
