I was talking to a local sand boa breeder at the last repticon and he almost talked me into getting a pair but I wanted to look them up online first.
He had said that sand is fine, but feed in an external tub. I think Robin picked up one or two sand boas from him.
On the same token, reading online, it definitely sounds like it's not require and you should probably stick to another type of burrowing substrate. I'm in now way trying to discredit what was said, just letting you know what I heard.
If I had gotten one, I'd put it on Aspen like the others.
