How to Choose a Yo-yo - Looking at Shapes (traditional/slimline-midline-Russell/butterfly)

This is the second of a two part series on choosing yo-yos based on axle types and shapes.  Primary yo-yos used in the demonstration by Luke Renner were created by:  Russell, Playmaxx, Tom Kuhn, Monarch and includes a generic red & yellow  plastic yo-yo (cameos by Hummingbird & Duncan). Studio footage filmed by Andrew Gomez in Northwest New Mexico 12/30/09 and footage filmed by Steve Renner 1/3/10. Yo-yo topic covered in this instructional video is the different types of primary yo-yo shapes. The three covered are traditional, slimline/midline/Russell and butterfly yo-yos.  Note: The Russell shape is included with the slimline/midline group; however this shape is considered unique enough to have its own category.    Music is a public domain jazz loop by Florian.
