This is the best thing you can do. Try it for yourself. There are enough big breeders and experienced keepers using it without issue, so you know your snake will not explode on contact with the pine.
I have everyone on pine now. I like it much better than aspen. Doesn't mold nearly as easily, it's odor protection is far superior to aspen, and it seems to be more absorbent as well. I think since you're giving it a fair shot, you'll be happy with it.
