GbajiTheDeceiver said:One other thought - "both fail lowest wins" is also a flawed mechanic, as it penalises the person with the higher skill. This is, IMO, even worse than halving, as it is far more likely to occur in general situations.
And if you drop that rule then halving works much better. That is what I am going to do. (... of course I just like situations where both fail - it will cause all kinds of interesting effects).
I also might use criticals in opposed rolls as well.
