I'm definitely not a breeder (so I didn't vote) and I hope it's all right to comment. Anyway, I have just one BP and I recently switched him to F/T. I used to feed live and heavily supervised (I even did it in a separate container that I hovered over...) but that didn't prevent a mouse from scratching the side of Freddie's neck once. And it takes just that once. I treated it just fine (it was small and there's no scar) but since I just have him, it was a push towards F/T. I switched him over right away and haven't looked back.

I can definitely see how feeding F/T to a huge collection could potentially be a hassle so, if I had more snakes, I would probably feed live unless I found a way to save time with F/T.
