Can I go back to Aspen shaving?

My ball 08 python has an upper RI in November and since then I've switched to paper towel as a substrate. My unlucky girl had a small case of mites too but I haven't see any since using PAM.

Anyway, can I got back to aspen shavings now? I think it looks much nicer and I didn't have any problems prior to the RI.

Yes, if the RI is cleared up, there is no problem with going on aspen.

Just make sure the brand you are using is not dusty or mixed with pine or cedar. :] Keeps the humidity better too, aspen does.
