There was a good post asking about Tesla Coil hits at
http://forums.monstersinthesky.com/index.php/topic,109.0.html, and while I am unsuited to answer that question, I am curious how others have been keeping track since the Lt. Manual was released. I think this could be a good place to get suggestions out there to help fellow players as well as improve our own games.
For mine, I made a multi-colored chart (in excel, sadly enough, hah) to go through the various modifiers depending on how many TC's were damaged. I then printed and cut those out, sticking them to both sides of a penny. -1 on one side, -2 on the other, and then a second penny for -3 and -4. Since all of the ship cards are pretty much just printed out, we've taken to weighing a damaged design down w/ the appropriate penny as a good reminder that A. there's damage; B. what that cumulative modifier is.
So, that's me...How do the rest of you keep track of those hits?
