If you think that'll be mass exp, you haven't tried chincompa's yet. Strange to see how people say that will make ranging too fast, without realizing hamsters are already 200K+ xp/hour! I have used chins. Cannons and chins are very different. Chins are mainly for fast xp, cannons for fast killing. Chins are only in a 3x3 square, cannons have a longer range :D
