It is possible even with recently published stuff that it was basically copied from out of date stuff, so try to find out about the author too. I know you said yours was written by professional breeders; I'm just mentioning this part for others reading this. I've seen web pages with recent dates on them recommending a night time drop to 75. I realized it had simply been copied from an out of date source, not actually written by anyone who knew what they were talking about.
Kc, I didn't want to post any info about the books on these forums, out of respect for the authors. From what I've read in peoples responses, it seems as though a lower temperature gradient is just fine, as long as your hot side doesnt drop below 85-90. I can see now why some professionals may have differing opinions, especially if they've been keeping snakes a certain way for a number of years without problems. I think I am still going to bump up his temp a bit on the cool side, only because the cooler weather is causing it to drop to 75 at times..

Anyway, I couldn't have asked for better responses. Thanks a lot guys.
