I need this trophy too! Weekends are better for me since I get on around 12pm Pacific (I'm in California). On weekdays, I'm on around 3-4pm. Late at night after 8-9pm (10 on weekends), I can't talk on the mic because I don't want to disturb my sleeping family.
I'm often in a group with some friends though so it's hard to pry me out of there, but I'll see what I can do.. maybe they can tag along as well. (:
My PSN is allicorn.
