When I did Snowstorm, the ones made by Larry Maples & Raven (I believe those are the names) I found to be the best for my purposes. Three stacks instead of two, broke easily when needed to break, and didn't "clump". Just be sure to wrap it up with one strip before using it. Some of them tend to be a bit loose. I used two packets, side by side. Impressed the audience. Pissed off the cleaning crew.
