I haven't used constructs much against monsters, mostly for puzzle solving, but the homing carts are fun. Used one in the big pirate ship under the island in the far SE corner. Also, although I fought three of the four regional bosses in entirely conventional fashion, the sludge boss looked like being a pain, so I put a template for homing-cart with hydrant on the front and construct-head+beam-emitter on top. Dropped one in the first stage, another in the second stage. Death by roomba (well, assisted by roomba), very satisfying.
