I may have read it on another forum, if I can find the posts I'll link them here but I'm not promising anything lol.5 and 7... really!? never seen one, I was actually pounding through the mk 7 thread all day yesterday (like just over 1000 pages) and didnt see anything. I swear these people keep em in window sils with direct sunlight
