as you know i love lindy but dont mind saying its where jive had its root! i started dancing 3 years ago (yes even before mj!)to 'glasgow jive' which ive always known to be a derivative of east coast swing as it is danced with a six beat basic. from what i know east coast is 6 beat although can be mixed with 8 beats as in lindy, west coast is eight beat but can be split into much smaller sections to fit the music!
mind you the ever helpful wikipedia do good descriptions!
