Hey guys, I have the Agent 18 Ecoshield. It's good, I like the design, but I find it wayyyyyy to bulky. I wonder if you have any suggestion as a replacement (THIN, great design, no silicone). I wonder which of these is the thinnest: Incase slider, Seidio Innocase or the Cozip case. Also, are they much thinner than the Agent 18? Thanks.
