James,
I was curious if maybe Paizo and Game Mechanics would be interested in joining forces and maybe a set of Game Mechanics INIT cards could be made up for STAP, so that GMs could print the sheets and have the various baddies all worked out on the oh-so-handy cards?
I would be happy to voounteer to help out if it could. (Since I am basically doing this anyways for my own use.)
Just a thought.
