Okay, so I finally get to see what baited traps do: they double the output of the trap. And I finally get to see what traps drop!
So now, I can label the trapper (assuming I have 9 traps and check them regularly (trapper can't make bait for 10)):
Income/10 sec:
Fur: 0.5
Meat: 0.25
Scales: 0.1
Teeth: 0.05
Cloth: 0.065
Charm: 0.005
Which is surprisingly competitive with the hunter. I think I'd rather have the hunter once I have my charm and better sources of teeth, scales, and cloth.
