Love the traps. Why not put the model traps at the side of the table during a jungle game, with absolutely no intention of putting them into the game, just throw some dice every now & then (with the occasional bit of under your breath muttering)
A friend once ran a Viet-Nam game (also a great place for your traps) & he had the payers sweating for several moves when one of them heard,' a metallic click under (his) heal' . He let them try all sorts of things to try & save him before revealing a rusting old bean can.
