I also don't like silicon and also the see through plastic as it make my phone bulky. However, leather casing still a must. It easier for me to take out the phone from leather casing than my pocket.

I heard there is a service to skin your phone and the quality is good and if you are a careful person, why not try the skin method. For me, because of my kid, I have to use a very good scratch proof protection so I end up with IS. Before, I always make sure to put my phone on soft surface like cloth or cushion and always put at high place so my kid can't reach it. Now, I don't have problem giving her to watch cartoon on my tube.
