Oh, I'm all for recommending what will work - 100% agree. But 2 hides is not needed, and to be honest, I've never understood why so many people regurgitate that information. 1 hide is enough. Many breeders don’t even use hides at all, as you know. Recommending 2 hides, to me, sounds like an idea that was conjured up by the manufacturers and resellers of hides.
That's all - just my opinion.
IT IS MY OPINION - that recommending 2 hides is silly. *NOTE* This is only MY OPINION. not a tested fact. (My original post made it sounds more like a fact, so I just wanted to add this is my opinion only)
