I fished yesterday and fought a barrel for just over 1.5 hours. The fish was at the boat 3 or 4 times but just outta gaff range. Well over 100kg! Was fishing just over the button on 37kg and backed off when the fish was close to the boat for obvious reasons. The fish had just about given up and was 30 foot under the boat, slowly crackin it up when pop!! My heart sunk! Found the mainline popped when the double meets the windon. The loop to loop connection let go. The dacron cut through brand new 80!! Not very happy at all. Doubt ill be using windons again for barrels...
