Revit :: Symbol Line Detailing In Family

how other people approach Revit (the joys of working as the solo Revit pioneer in the practice)I am in the middle of putting together various families - and have been experimenting with symbol lines for the detailing at reveals / heads etc.
 
For the moment I had simply used masked regions to create the joinery of frames, beads, architraves etc. which works fine, apart from not being able to use any fills at family level - leaving it to call-out drafting to add the detail in the project.
 
I tried the alternate of using Detail Components within the family (a simple rectangular joinery section) with shared parameters so that it can be driven by the host family - which allows drafting fills to be used.
 
It looks better and will save time placing fills later on to call-out details.
 
But - is there any impact on performance in doing this (every section now shows the fill when set at 'Fine') - is this a standard approach, or am I better leaving the symbol linework as hatch-free in the family itself - and leaving it all for addition in individual call-outs ?
