I don't use top feeder either...
just casually it sounds to me like it is one of those 'you are damn if you do and damn if you don't' thingees. the difficult thing in these cases is the decision as to when to bite the bullet and do the dirty deed. I would have the tendency to "get 'er done now'" thinking that the sooner you can remendy the problem the faster the hive can get back repairing the damage.
at this time of year I tend to leave unfinished supers on unless they are bone dry. they will be soon enough anyway.
