I feed F/T. I find a lot of people on this forum attack the "safer for the snake" reason for frozen thawed. Personally I feed F/T for the same reason I don't feed my cats live mice. I am not interested in keeping rodents, I keep cats so that I don't have to have rodents in the house. Both my snake and my cats do fine with their respective substitutes for live prey. Its really just a matter of convenience. I went down to the basement last night and got 2 mice and two steaks out of the freezer. The steaks were for me and my girlfriend.
I am lucky though, my BP strikes and constricts as if the prey were live. If she stopped doing that I would consider switching her to live.
