From some angles the stock hat looks ok, it's just from others that it doesn't look quite right. Does anyone know how the HT hat sits on the SSC head!?
The HT one isn't much bigger either, you'd think someone would have researched it and got it right by now. After all, it's what makes Indy Indy. George Lucas wanted you to see that silhouette and know instantly it was him, you see this in Nepal with the "Hello, Marion.." scene.
