George,
the problem so far has been the teeth, the fish swims back and forth across your field of view and with each turn the line crosses the teeth... When caught they snap their jaws shut on the steel, keeps you on your toes.
Rad, It's good to know I'm not the only 1 with that problem!
When the pacu were in the 1-2 pound category, I always hooked them in the lips. Now that they are bigger, I guess they suck the bait in quicker, and are able to bite the line. It's a dilemma. I don't want my pacu to grow a beard of hooks, and I don't want to bream fish with a wire leader. I think I'll try the Berkley line and see what happens. (Thanks George and GW!)
