As for dates, most would say a weekend...I'd be fine with that as long as it is not a Friday/Saturday night...Sunday midday would be awesome, but obviously it's not just me yall care about...lol.
I think stock maps are a good idea...fairly glitch free, even playing field, and not much to learn as far as map dynamics and positions...although I love custom maps too...lol. As for perks, if we're going to enable them, I think it's only fair to enable all of them or none of them. As much as I hate the RC-XD and think it ruins the game in CoD4, I think most on the CoD4 side would argue for it...lol.
