On a recent non-TT trip to the island, exploring for alternatives to the normal circuit, we found this road that took us up and over an area of high (for IoM anyway) hills with views to the coast in 3 directions. Some beautiful newly laid tarmac and plenty of visibility ahead. One or two tight corners, but this was an absolute blast. Had to do it several times. The tarmac on the link road to the south is a bit poor so I haven't included that section in the route, but it's worth the pain to get to this particular section.
