Line Diameter vs Breaking Strain

I wandered down to a couple of fishermen while having a coffee this morning on Fraser. During the chat one of them was explaining he was having nothing but dramas with his line being swept around and that's why his mate was catching all the fish and not him. On inspection its was bloody thick stuff! But it was recommended by a shop in Brisbane and he said its the right breaking strain he uses, so it must be ok …….
After making another coffee I decided to get the go pro out 😆. This is something we see everyday at GFHQ. People looking for new mono for a reel without ever considering diameter. In some instances such as rock fishing or fishing heavy structure thicker diameter lines are necessary. In almost all other scenarios, choosing the thinnest diameter in your breaking strain range will yield better results.
