I've done 6/9 gold runs so far as enhancement with a group of DK tank, Priest healer, Ret paladin and a mage. Only missing MSP, Brewery and GoSS, with MSP practiced with only a good run from gold and half the group with GoSS gold.
I'm curious what spec and the makeup of your group you're doing CMs with and how well it's gone, have you gotten gold or only silver?
