The Alleycat 650b, Loop Diggers edition yo-yo in dark blue was originally made for the Core Concepts yo-yo team. At the time, approximately 30 of this model was supposedly made, with a handful being sold by YoYoExpert on July 19, 2018. Yo-yo also came with an Alley Cat Loop Diggers animated patch, exclusive to this blue version only. A second, limited number of Loop Diggers was released the next year in 2919, but in an army green color. And, again, a third release in army green, sold exclusively by YoYoExpert, in October 2020.

The Alleycat 650b addressed some play issues that the original release suffered from. For this 650b release, the diameter was reduced from 59 mm to 57 mm and the string gap was reduced from 3.4 mm to 3.1 mm. These seemingly small changes were made in an effort to improve the yo-yo's looping ability and playability when completing original yo-yo tricks such as Shoot the Moon. Compared to the original Alleycat, the 650b version has softer edges and the protuding hex hub was eliminated in favor of a smooth, relatively flat hub lump.

The initial release of the 650b version occurred on March 22, 2018 and came in anodized colors of black, purple, teal, green, black/purple fade, silver with black splash, and a green/blue fade. For some reason, only the green/blue fade came with an imprint on one halve that was composed of "Alleycat" and the Core Concept Yoyos graphic of a speeding bicyclist.

Uses a heavily lubricated size A (5x10x4 mm) ball bearing axle and, new to this version, Core Company's own response pads. Designed in the USA and made in China.

Original retail price: $60 US.
