>>5256425The Classics Hotrod mold is quite dated with limited articulation. He doesn't use 5mm pegs so that's a letdown.
There's the Energon Rodimus which makes quite a decent Rodimus Prime, though his combined mode is horrible.
The Japanese Cloud Rodimus is a repaint of Thrilling 30 Springer. Springer is a good mold so this may be the best Rodimus. But the exclusivity may make him expensive. I skipped him because I don't need a third version of the springer mold.
