A PC minecraft seed for 1.8.3 that has tons of villages?

They all have tons of villages. Different seeds have to do with the distribution of biomes and water/ocean size and location. But if you examine the worlds out to 20,000 blocks or so with different seeds, you realize that the probability of villages and temples is about the same.

The biggest difference with different seeds seems to be the size of the water biomes. Some have huge oceans, some have a lot of little ponds, some have little water biomes. In the land biomes, village and temple distribution is pretty constant, you won't find a see that gives you more or less.

Try a seed that has the land/water makeup you like, and then go look for villages.
