They look great....outstanding growth through the winter period. It's hard to tell when they are smaller, but I think your first photo MIGHT be a female.....don't panic, I'm just going by coloration and opercular tab shape....very hard to tell.
Just tell yourself that you WILL have some females present. It's unavoidable in this situation. Keep all vegetation and cover to an absolute minimum, and you might throw a few LMB in there to help you sleep better at night. Single sex Bass would be nice, but I don't worry about it....they'll eat their own offspring also, and I see VERY little LMB recruitment in my pond....simply not enough forage for a population of LMB.
