Should I get a SlickWrap for my iPhone 4S?

I currently have had an Incase Slider Pro case for nearly a year and I also have a ZAGG Invisible shield on it. Is it worth it to replace those two things and get a slickwrap? I hardly ever drop my phone.

I had two different SlickWraps on my 4S over the course of the two years I had it (just got a new 5 the other day!), and they were awesome! I had a wood one and a painting, and both were really cool and realistic. I never dropped it, but they protected it from scratches well, stuck on the phone nicely, and tricked a bunch of people into thinking my phone was really wood xD
And for $20? Definitely worth it.
