Hi, ive been looking at baitcasting reels and i was just wondering what the difference in baitcasting reels design would be between some thing like Shimano Curado(http://www.tackledirect.com/shimano-curado-baitcasting-reels.html) and Shimano Calcutta(http://www.tackledirect.com/shimano-calcutta-b-reels.html). Is the Calcutta type ment for heavy fishing?
