Silver, iron, virgin blood, fire, bullets tothe head, sunlight, holy objects, garlic, and belly wounds are all far more common that "true" emotions. (at least as far as I can tell in this universe)
I'm not going to bother weighing in on my opinion of the actual point total, no one really cares about other people's opinions on catches (I bet they vary table to table).
I think it should certainly be less than +3, likely less than +2, but whatever.
To answer the OP. Ask your table. I'd likely give a +1 bonus to having multiple catches even if they are all rare. (I'm likely a minority in such an opinion). So if your table says +0 try for +1, if they say +1, try for +2...and so on. I wouldn't bet on getting that bonus, but why not try?
