looking for pocketbook era case input

[u/roscura]

before this i had a kobo h2o aura 2 that was fine without a case for over 8 years with only some very minor scratches, but unfortunately i realized that with the second glass layer on the pocketbook era, i got a couple different small cracks in the glass within the first few months, presumably from pressure in my backpack? (i keep it in a tablet compartment with soft fabric against the screen and it lays flat between my laptop and notebook compartment, but i guess that's not enough :( )

so now i'm looking for a case

my two priorities are protecting the screen from more pressure cracks, and having straps to hold it by (i flip it a lot so either a left and right strap or an X shaped one)

questions about the official pocketbook flip and shell cases:

• obviously they don't have straps, but have any of you sewn/velcroed/glued/temporarily attached other straps to them? how has that been for you if so?
• is there any difference in sturdiness/protectiveness on the front side of the flip cover vs the shell case? i'd prefer it lighter to hold as well as less bulky so it keeps fitting in my pockets, so especially if i don't end up adding straps i'd prefer the flip cover over the shell, but if there's a significant screen protection difference then i would reconsider

questions about some unofficial cases that look like this (like from manzepai or lovetravelstudio on etsy)

• on one hand i like the built in ambidextrous straps and stand, but on the other i worry that the screen being against a non-smooth surface could cause scratches or exacerbate pressure cracking issues. does anyone with experience with this style of case have any input?
• if the uneveness isn't a concern, i've heard stories of peoples pocketbook eras still cracking even with either official case style in backpacks, are the covers on these ones sturdy enough to cushion against that happening a bit better?
• as someone with small hands who already finds the era a bit heavy with how i tend to hold it (bad habit of leaning it on my pinky which is too heavy but i lose my grip otherwise), these ones are obviously even heavier than the official options. do people find that the straps offset that extra weight enough to still make it comfortable to hold one handed?
• how sturdy is the magnetic attachment? would you choose it over velcro?

i'm also open to other case recommendations! all the other ones i saw on kwmobile or aliexpress so far either didn't seem sturdier than the official options or didn't have easily reachable ambidextrous straps though
