I bought an xtremeguard (wet application) screen protector, so I'm not concerned about scratching the phone when it's face down, but that call into question if the screen protector will get lifted up when I insert it into the case (like my current 4S Incipio feather/BSE screen protector). I used an Otterbox for about a month, but I couldn't get over how fat it made the entire device. The ballistic (and Spigen) case seem to be a lot thinner, but I'm worried about the screen protector lift, and drop protection (the Incipio Feather case has successfully protected my 4S from 4 significant drops).
