I can't imagine it lagging too badly....Personally, Having 80 values in a string is MUCH nicerlooking than having 80 flags take up the whole window...but that's just my opinion.
Or, like Kam said...do something like
NPC Code:
if (playertouchsme) {
setstring client.chest_#F_#v(x)_#v(y),open;
}
That Would actlike a flag, and instead of checking if it's true, you'd just check to see if it's "open"
