I had the Rhinoskin Aluminum for my X5, so naturally I went with Rhinoskin Aluminum for my X30. I'm just a little weary about the aluminum bending sometimes and possibly damaging the unit. Has this happened to anyone else?
I would go with metal if you want something that will last. I'm rough with my handhelds. They go on my adventures, in school, home, biking, driving (yes, my driving is an adventure

).
If you are a rough person who likes to play, get aluminum.
