Assessing Flex Based Application

[spammailme () gmail com]

I am preparing to test an application which is built on flex, and am wondering what techniques I can use to test the 
site.

I use proxies, black box vuln scanners, and common sense yet are there any tools I should be using?

Been looking at firebug but not getting much out of it (yet). 

What are you all using?
