My whole collection is on F/T. Most bp's will readily accept f/t if it is offered correctly, sometimes it takes a little trickery, but they convert, now am I saying that every single bp out there will accept f/t, nope because there are one or two here and there that wont. Even if your bp readily accepts f/t, it is still possible that a day will come when you have to offer live. Thats the nature of dealing with these animals.
