I know that glancing blows don't proc sneak attack damage so the THF feat chain isn't helpful in that department.
But for a Rog 13/Monk 7 (or Monk 6/Ftr 1), would the THF chain be helpful when soloing to dish out more damage when I can't get SA dice (like against undead for example)?
Otherwise, would the Spring Attack chain be worthwhile? I already plan on taking Dodge to get Ninja Spy I.
