The 10th East at Royal Melbourne - a 510y par 5- would be one of the very best 300-330 yard holes in Australia. Drivable but with so multiple options, many of them dependent on where the pin is cut.
In a way, it's a real pity to see the long hitters hitting drivers and seven irons, completely negating the strategy. The only way to regain it for them would be to make it a short 4.
