What brand for the back protector? I am tempted to just go with the tpu bumper case and a front screen protector so that I can feel the wood.
I used to use Skinomi, they have good durability. They have clear front, back and side skin. What I don't like is that you have to be very careful with installing them and it's harder to get perfect since the adhesive sticks very quickly away so there is more potential to get it wrong on your first try. Skinomi skin is thick so it have good healing properties too. Like dbrand, they have 3M sticker for the back, they're basically the same material as dbrand and cheaper.
Now I use XtremeGuard since they are so cheap, the touch feel I think is a little less smooth than Skinomi, but very usable. They're also a lot easier to install since they don't stick so fast so you have time to adjust the placement.
You just have to be careful with wet applied screen protectors to not damage your phone or trigger the water damage detector. I guess its less of a concern with the Moto X. Just have to use the least amount of water as necessary and put the phone over a napkin or towel to dry it right away.
I love using wet applied type though, they can last for months or a year depend on your use. They are excellent at hiding display scratches, so if you have used phones with screen scratches, if they aren't thick it'll hide them all. Also they gives good grip.
