Some great information coming from this discussion.
As stated do what's best for you and your snake is always the priority, I wanted to move up in prey size but my reptile guy told me to wait because she has a small head/throat, so feed x2 instead of 1 large until she grows a bit more.
Again I'll say, a discussion on this forum would be an all out brawl on most others (I can only speak to non snake related forums), it's such a relief to be a member and learn from all your experience. For that I thank you all.
