Need help shortlisting diamonds after 3EX and HCA

[darknezx]

Having thought long and hard, I have decided to take a plunge and purchase online. Am looking for a 0.6, E/F, VS2.

Have shortlisted 8 diamonds, but don't really have a clue how to shortlist as they all seem to be decent in 3EX, CA, PA, and HCA:

The third one seems to me the most symmetrical and the AGS report seems to show only slight leakage at 2 oclock position. The fifth one looks rather good too. Any comments?

Many thanks!
