Stiffness of TCS Voyager leather case?

[naddy]

I recently bought an HP-15c CE as a replacement for my aging original HP-15c and I'm happy with it.

The included case is a bit floppy, though. Rather then just sliding the calculator in, I feel like I'm stuffing it into a sock. The original 1980s case is noticeably stiffer, making it easier to slide the calculator in and out. I see that The Calculator Store is selling true leather cases. I would expect those to be stiffer, like the original case, but I thought I'd ask here. Are they? For those who are sensitive to such things, how does the feel compare with the old HP case?
