I am relatively new to carp fishing but not to fishing itself which I have been doing for over 40 years and I must admit to being totally confused when it comes to main line strength. I have always believed that the nearer you get to the hook the lighter the breaking strength should be as that way if you do get a line break you are losing as little of your tackle as possible. This, however, does not appear to be the case with carp fishing - This thread advocates 12 to 15lb mono, but if you read something like "The Guide to Modern Day Carp Rigs" then most of these rigs are constructed with 20 to 25lg hooklinks which are then attached to a leader of similar breaking strain - Surely this is a recipe for disaster as any break must come in the much weaker mainline - Or am I missing something?
