Fished st Lucia this weekend,caught three small kingfish,one queenfish and a few underside shad,on Sunday I slid a live 3 spot pompano,the rod was in the stand for about a hour,then the rod jerked and I noticed my line went slack,when reeling up I noticed my leader .70mm(kingfisher) was cut above my stopping ring. I was using a florocarbon leader so if it was a shark my leader on my sliding trace would have been bitten of,here my entire hook trace and sinker were lost, any idea what could have happen
