What line size do you guys use when deep water cranking in the summer? I understand that when fishing cranks on mono the smaller the line the deeper you can get. Is the same true for fluorocarbon? It seems to me if fluorocarbon sinks then the opposite would be true meaning the bigger the line the faster it would sink? I just ordered some Vicious 15 lb for the first time and am wondering if I should have got 12. Thanks
