Make sure you do a good cleaning run in the still if you have not.
If I were in your shoes I would do 6 stripping runs- save everything from those runs and do 1 final spirit run.
You can do 6 stripping runs in an afternoon if you have the time- or split it up into two sessions.
Fill the still- crank the heat until you have a decent stream and collect down to 10-20%-
then dump the still and fill it back up and run it again- until all of the mash is done.
the next session add all of the “low wines” (everything collected from the stripping runs) and do a slow spirit run.
I think that would give you the best final product and maximize time and effort.
