BBC Wales Sport looks back through the Six Nations archives to bring you a dozen devastatingly good Wales tries.
They have been selected by former Wales and Lions flanker Martyn Williams, and 'Nugget' will join BBC Wales rugby correspondent Gareth Charles for a special radio programme to explain his choices.
The pair will also assess this season's Championship, which starts with a mouth-watering clash between Wales and England in Cardiff on 6 February.
Ryan Jones started and finished this Murrayfield beauty, and triggered a rout of Scotland that had Wales fans daring to dream of a potential Grand Slam.
