Crucial's "Half & Half" made out of dyed Delrin. Crucial began in 2007 by Paul Yath, a multi-champion yo-yo player and former member of Team Buzz-On of Buzz-On Industries.
You can swap out the SPR kit on the Half & Half to install different bearing sizes or response pads. The SPR Kit in the Half and Half is a size C flat bearing with stock white Crucial-branded "Ghost [response] stickers". Ghost stickers are the same size as K-Pad Large Broad response pads.
The body design of the Half & Half is very similar to the DV8 yo-yo by Buzzon Industries. Also, the Half & Half went through four different prototype models before Crucial released it in August, 2010. The Half & Half coloring in this exhibit may have been a prototype or an alternate released version. Raw Delrin is either black or white and the Half & Half was originally released in white. If you know more about this colored version, let us know!
Also worth noting is that the Half and Half was sold standalone; no packaging.
