[Urgent] What is the most unreadable string which can be translated to a barcode (self.techsupport)

The reason I'm asking this is the company I work for develops an application which has a barcode reader functionality. The device we develop these softwares for has a very limited resolution camera (2MP). Now they want me to set a benchmark for the maximum length barcode pattern which is scannable. So what I'm trying to do is use an online barcode generator of CODE-128 and then feed various length strings to it. If I knew what pattern results in the most dense/unreadable barcode I'd be able to create different patterns using that.

Code 128 has three modes, which are described on wikipedia

try finding a sequence that makes it switch modes as often as possible, that'll make it harder for the software.
