If you were the representative of a small district you would face exactly the same problem as with big districts. You would still face the interest trading that all politicians face. I would imagine that committees would get bigger. Hopefully with more politicians you would get more people who actually knew about the area that they were on a committee for. The main thing is once you got rid of the need for money the desire to be on a powerful committee would decrease.
