Medusa West has a straight first drop, East doesn't. Dive loops are angled differently. East has a cobra roll, West has a "sea serpent." West has a flatspin directly after the block, East has a helix. West doesn't have interlocking flatspins, East does. West has two helices, East only has one.
I think that's about it, anymore questions, I'll try and answer 'em. :)
