Paper pellets vs. aspen, the importance of burrowing?

[Steveo]

I don't think there is anything wrong with using aspen, though Carefresh Ultra is my preference. The garters do seem more confident and secure when they can burrow. Most nights I come home from work and it's just heads sticking up out of the substrate.

I do the spot cleaning when they're in their feeding containers. Since they are burrowing I usually have to turn everything over to find all of them anyway.

Ah yes, I've never tried carefresh so I was thinking to stick with what I knew. I also heard it was more expensive than aspen. Definately something to consider though.
