I feed nothing but frozen. Live is too expensive and only my babies getting started eat live. I just buy frozen in bulk and have 2 large freezers full of rats and rabbits. I used to breed my own rats and feed live but the time and energy spent cleaning and feeding as many rats as I would need isn't worth it to me if I can just feed everyone f/t. Especially working the hours I work, I usually don't even have the time it would take to clean the rats.
