Do you release the breakaway weight when deep dropping for broadbill swordfish?
It all depends on the current. I have used both methods of breaking the weight away myself when it gets to the bottom to let the bait drift and letting the fish break it with about the same success rate.
I do find that by leaving the weight attached I know where my bait is at all times and can feel any bites which can be an advantage.
