Okay. Help me decide here.

[Homebody]

I have a young bredli. Now that he's out of quarantine I want to move him to my 40 gal front open enclosure(I will upgrade to a 4x2x2 or bigger when he gets bigger, been debating on ordering or making one)

So I've kept BPs prior to him. I've kept them all on either paper towels or the repti liner from a gecko and his pj's. Which is super easy to clean lol.
I've been debating for when I move my Bredli to the 40 gallon to either stay with the repti-liner, start using eco-earth or kind of in a way do half and half. One side repti liner, one side eco earth.
I feed thawed and in the enclosure. I've heard people talk about incidents where their snake ingests substrate so I've stayed away from loose substrates.
I guess I'm just looking for someone to ease my mind about using loose substrate.
Also, if anyone can show pictures of their carpets enclosure that'd be helpful! And tips! I currently have a few hides and a few pieces of driftwood, but I want to get a bit creative.

Thank you in advanced!

For my Children's python, I use half repti-carpet and half loose substrate (paper shreds). Pics of my set up:
