I'll look into these a little more closely when I have more time, but as far as I'm concerned, anything that results in more votes actually electing someone will be a change for the better. The fact that an average of 60% of voters vote for someone who doesn't win is discouraging at least and anti-democratic at worst. I like the preferential first-past-the-post mixed with proportional representation best, because it retains its regional flavour without being totally blocked in by it.

The regionality issue is the other reason we need change in this country. The NDP and the Bloc got the same number of actual votes nationwide, but the Bloc has more than double, in fact nearly three times, the number of seats. The same thing happened with the Conservatives in Ontario; they got about 30% of the popular vote but a lot less than 30% of the seats, because the guys who got 38% took home all the prizes.
