So this is my first time I could get my hands on the stuff and I figured why not try it, I've got two choices, he calls one "white dream sand" which is obviously white, and the other one is an off yellow color and you can definitely see a color difference, the white is a bit more expensive. Any ideas for a first timer? Should I go with the yellow or white? P.s. I know it's legit and the guy has tons of people raving about the batches he's got. Thanks!!
