I've had the Coyoteworks case for a couple years now, and it's just now beginning to break in. It still looks pretty much like new, it wears like iron. I had the steel skid plates added too, and that seems to be about the best protection against bag drag you could buy.
On the inside, the floor of the case is a smooth piece of ABS plastic, so your jepps never come in contact with the hardware for the bottom of the bag, preventing your jepps from being torn up. When I bought mine, it came with a lifetime unconditional replacement warranty, including bag drag.
If you decide on the coyoteworks bag, I found an extra side pocket to be worth it, but the leather organizer, not so much. it's sewn flat, so you have to work with the leather to get it to stretch to hold anything, and with no straps to hold anything in, my pens/logbook/passport etc tend to wiggle loose if I'm not careful.
The only complaint I have is that with all the leather and steel, it's pretty heavy to tote. I imagine some women might find it too heavy, depending on how loaded it will be.
