The best peelers to use are indeed the females that have moulted and are protected by harder males as there pheremone deters other crabs from praying on the soft females due to a mating enzyme that males and fish find very attractive in two different ways. Usually happens about 3 weeks after the first main male moult of shore crab.
Good luck with bringng some on early.....might try this myself at some point.
