Hi Dan. If I understand your question. You are asking whether you should increase the exposure time of your subs to get more detail and you want a dark library to match.

Total exposure time is more important than longer exposure times. Optimise your exposure time for your sky condition and take as many subs as necessary. Then take darks of the same duration as your subs and preferably at the same temperature.
