How interesting.
I may know less than you, but you seem pretty darn sure that you know more than anyone else here.
Well, why don't you give us some solid reasoning and facts? Your previous experience and collection perhaps?
Through common sense (and what I've heard about from people here and there) usually power feeding is meant to make a snakes growth rate increase. There may be different forms of this power feeding, but it may only be meant as used as power feeding specifically on occasion. (am I making any sense?)
If your feeding a snake every other day to get it up to breeding size, I would believe that to be an inappropriate form of increasing growth rate quickly and ineffectively... naturally I don't think snakes are meant to grow that fast or eat that much. I don't know this as a fact, but would assume that it's probably hard on their intestinal tract as well as their heart.
I donno, thats what I think.
