Don't forget that being able to flip-flop can also give you better results 
even if you would have succeeded anyway. If your skill with guns is 50% and 
you roll a 14, you'd normally do 14 damage. If it's your obsession skill, 
you can flip-flop it into a 41, still hit, and do almost three times the 
damage. You can get some pretty impressive damage rolls at higher skill 
levels, though it's not a big deal with HTH damage unless you take some 
cherries.
