I'm for anything other than 50-x. The original 45-2x is still my favorite just because I'm so used to it, but 45-x is fine as well. I just don't like removing the risk factor all together. I've never decided to take the favorite when I wanted to take the underdog because it might cost me too many points. If I'm taking the underdog, I honestly think that he's going to win the match. I'll make the same prediction under a harsher system or a less severe system.

You can bring up how taking Mario with 50% nets so many more points than taking Samus with 50%, but I don't like the idea that, if I choose the correct winner with 54%, and he wins with 51.5%, that someone who didn't even choose the correct winner and hedged with 50% is going to score more than me.
