I use this one and really like it. It’s pretty slim as well and has a nice feel to it. It’s held up pretty well. I can take it off rather easily from time to time if I feel like holding it without a case.
In regards to your current case I have an idea. I think the Libra is easier to hold with a case but don’t really like the feeling of the front cover hanging as I read. What about cutting off the front cover portion of your existing case and using the back as a grip/protection for the back. Just use the other case with the front cover when you are traveling or putting it in a bag to protect the screen. Just an idea.
No problem! I’ve got a couple cases. This one is my favorite.
