The Big Question: Sand vs Everything Else

[tHeGiNo]

Ok, after reading a few threads I deemed it necessary and useful to myself to create this topic. I understand why sand is a substrate which should be avoided. The reasons are clear to me, so this does not need to be stated. However what I am looking for is an alternative. Not paper towl or news paper. I therefore must ask the big question: What is the best substrate for Pogona Vitticeps? By best, of course, I mean an efficient, clean substrate which tends to the bearded dragons needs before the owners needs. Which is how it should be. I ask that you use factual answers, and state WHY the substrate in question is the best. I am sure this will be a great debate, and it would be great to get some of the experts like EyeSpy in here. Please do not just post a substrate and call it a done deal. Expand.
