All you need is a Cherry Bomb (A-Line works best)
and 2 Viper or Cobra Shells
All you need to do is pop on the shells to the CB and you have a great yo-yo. You can also preform DrJ's Homemade SF mod for even better play! It's a heavy, long-spinning yoyo that's great on and off string!

For this mod, all you need is a Yomega Saber Raider. First, unscrew the SR and take out one spacer. Then, with the spacer, put it back in, but flipped. The smooth side of the spacer should be touching the bearing, with the grooved side showing. This mod makes the Saber Raider play amazingly well!
For this mod, all you need is a Yomega Raider. This mod can do 2 different things. To make your Raider a string trick killer, preform the Saber Raider Mod. If you want it to be a great looper, Instead of flipping one spacer, flip both. This makes the Raider play much like it would with plastic spacers.
