The difference between Thermal and Flash and a top tier stamina wheel is the shape. Thermal and Flash aren't perfectly round like a traditional stamina wheel, such as Duo. It's symmetrical, just not completely symmetrical all the away around. So if you were to fold it at a certain angle it wouldn't line up perfectly.
But Thermal doesn't have two imaginary wheels with more weight or even shape.
