I have the Charm Me in Black Crash and it is beautiful. I love the crash leather and I wish it came in more colours. I love the Crash Pewter but it isn't me.
The crash leather is definitely smooshier than the other leathers BE uses. I've got 3 other BE bags and the crash is beautiful.
All 3 colours you are considering are beautiful (Petrol, grey and black crash) but I vote for the black crash.
