Much as I love the new design for Sunstreaker, I hate that little pin head he's stuck with. Hasbro has been leaning more and more into the cartoon aesthetic, but for me the "real" Sunstreaker will always have the giant mellon with its massive bat ears. Universe '08 got it nearly dead-on, and that mold remains my favorite Sideswipe...but I always kind of missed the Lambo feet and wider body when it came to his brother. Turns out, swapping heads was easier than I expected. They use the same size ball joint, so it's just a matter of a few seconds to give Sunny a more toyish head. What took a little longer was modifying his chest cavity, so that it stows completely in vehicle mode.
