Emperor Scorpion Substrate?

I myself just use Eco-Earth, it's a very good water absorbent and it doesn't dry out fast, even when exposed to direct heat lamps and such, also the reason people are opposed to using heat pads is: Emperor Scorpions are Burrowing species, and a lot of the time they'll end up burrowing into the substrate and cooking themselves due to the heat pad, also your Substrate would do just fine, however as I said I use Eco-Earth, I much prefer it over other Substrates for Rain Forest scorpion species.
