The trolling for pelagics bit takes out the 200 size straight up as you run a serious risk of spooling. Apart from that it may just come down to price and what you prefer. You should be able to pick up the Curado cheaper plus at that size it would probably be more user friendly when casting compared to the Calcutta. I had a 200 Calcutta and it was great for casting but unsure on the bigger models. I now have a Curado 200 E7 and very happy with it.
