I feed all mine frozen, if I had access to the amount and size of live feeders I need on a weekly basis I would feed live,
Saying that I did acquire a 600g live feeder, it took a few months but I did switch her over to frozen, now she smashes frozen every time. When I did switch her she didn't loose any significant weight.
I think it's all down to personal preference but as a previously said, every keeper should be willing to feed live if the health of the animal depends on it
