Favorite substrate?

Whats your favorite substrate for racking systems? Just want to get some opinions, I'm thinking of changing mine.

Papertowels, Newspaper and Sanichips.

Packing paper

Paper towels, newspaper.

Newspaper. I can just go into one of the dorms and get a stack of school papers for free. Hardly anybody reads it and there are always tons of extras so I don't feel too bad about it.

I use paper towels for my BP and RTB and aspen for my East african sand boa and western hognose. They like to burrow so it is more ideal for them. Although I do put papertowels underneath the apsen for my hognose because he won't burrow unless there is paper towels down too. He is a very strange snake indeed. I need to get some pics of what he does to his aspen if there is no paper towels. It's funny.

I'm using paper towels too, but its annoying. mine bunch up the paper towels, or get part of it in the water so that the entire enclosure gets soaked in a matter of minutes :mad:

I use mostly newspaper in my racks. I find that if I crumple up and extra piece and throw it in they are less likely to try to burrow.

im using zoo med desert snow for my young ones and newspaper for the adults

I'm going to try using yesterdays news, see how that works out
