I usually select the Use Place Styles option.  I rarely use the Short Place field option.  Most of my Selected Place fields are from L2 through L5 with an occasional addition of L6.  I usually de-select L10 unless I use it for a very rare special purpose where the other fields are already used.  I usually have use the At preposition, but that is a user preference partly from knowing how my Sentences are designed.  I find “At” to fit most default Sentences and when it doesn’t, I will have modified the Sentence to not need the preposition.
