How about Focused giving you on opposed duel and letting you ignore one on the damage flip, thus making a straight flip just as common as it already is, but taking that bit of extra oomph away from accuracy difference of 6+?
Maybe add the reverse to using Focused defensively by letting it ignore one from the damage flip after checking the fate modifiers (so as not to limit the occurrence of straight damage flip, but still having a slight overall effect in reducing damage dealt)?
Or perhaps this would add a level of complexity to the rule for very little gain, I do not know, but this kind of an amalgamation of suggestions in this thread popped into my mind on my extended period of prolonged procrastination.
