I currently feed both, all but one eats f/t. The live is a hopper. For those eating f/t, I plan to keep it that way. For the one that won't eat f/t at this time, I plan to switch after a few more meals.
I don't think anyone should be too quick to criticize those who do or don't use live feeding unless that person is doing it for the joy of watching animals die. One should try to switch but if it won't take no matter what, and it is losing weight, so be it and try again later.
I truly believe that there is a small minority of snakes that just won't compromise no matter what. Some picky eaters like bp prefers live only and forever, others wants white vs black fur, and those who only mice over rats.
