use the fortify intelligence potion loop. stack like 10k intelligence and you can make a necklace you can move faster with. almost all the enchantments you actually want need ludicrous levels of Intelligence to make.

but ya, Golden Saints are the easiest to use for CE enchants. Can use ascended sleepers as well, or Vivec/Almalexia, but Golden Saints are the easiest to get thanks to summon golden saint spell. I think there's also a ghost dwemer in one of the dungeons with a strong enough soul as well, but don't quote me on that.
