I agree with everything James wrote, I'd just like to make an addition.

In addition to losing "localness", some would argue for smaller district magnitude for two other
1) A moderating influence on the legislature. By requiring every elected candidate to have a
significant level of support in some area, we reduce the chance of electing more extreme
2) Simplicity for the voter. The fewer seats to be filled, the less candidates the voter has
to vote for to ensure exhausting his or her ballot, and the less research the voter has to do to
vote in an informed manner.
The first point is a bit more controversial than the second. At any rate, I'd gravitate towards
around 7 candidates per disctrict. This is a general rule and I'd allow for exceptions. An
excellent example of an exception would be New York City, where it makes sense to just have one
district with a dozen seats.
