I've never had an issue w/ the damp paper towels being ingested plus a lot of people here use paper towels as their substrate so I have a hard time agreeing with that. I will agree that they dry out quickly so you would need to refresh them at least once in the morning then again at night. The moss in a hide box is better for holding humidity but it can be hard to remoisten as the snake likes to stay inside while getting ready to shed. In my experience at least. I will also say that I don't generally have shedding issues, thanks to NC weather, and have only done the humid hide trick twice and the paper towels once.
Oddly enough I just checked on mine and found my Fire shed today and I didn't even know she was in a shed cycle, the shed was perfect. So it does get easier as they get bigger, she's pushing 1000g's.
