I had the VZW hard silicon case, liked the way it felt, but it would not stay on the back, and I didn't like that it covered up the buttons, and it did make the phone feel a little bulky. I am now using the shell/holster combo. Much lighter, less bulky, stays on and doesn't cover the buttons. It does make the phone feel less secure than the silicon cover, as it feels more slippery, but I can now clip it to my belt, which is a plus. Still searching for the perfect cover. A nice combo of the two would be perfect.
