Pipes is the expected repaint/retool of Huffer that's a fun figure and a nice change from Huffer. Puffer and Road Ranger are nice homages to interesting periods in Transformers history. Puffer's deco is based on an international release of the G1 Pipes toy, while Road Ranger is an update to an Ehobby GoBots tribute release from the early 2000s. While all the figures are fun, if you're just looking to experience the molds, the Golden Disk Collection release is a great way to sample the tooling.
