Ok... Mach 5. It is a neat looking trick. It results in the yo-yo seemingly staying still while your hands rotate around it.
You land split bottom entry.. then do the first somersault of atom smasher. Then you take your free finger, and do a second underpass (same direction as the first one), but be sure you only bring one string under (the one that isn't directly connected to your yo-yo finger).
No.. after you catch that string and bring it under, don't bring your free hand towards you. Just keep it under and pull your hands apart so that the strings are taut. Then rotate both hands around (braintwister direction) until you are back to where you started (yo-yo hand on top.. free hand on bottom).
Then you bring your free finger back up to undo that hold, and can dismount or continue with atom smasher.
When you do that underpass where you catch one string, you can either just move your free finger away from you and miss one string, or you can bring it over the top of your yo-yo finger and grab it that way. The same applies for when you get out of the trick.
Hope that makes sense. Also keep in mind that this trick has the string wrapped around the axle strangely, so be carefull or it can get knotted up. Smooth yo-yo also helps a lot...
