I always feel like I should be using one when not getting bites, but I love to hate them too. They're adaptable to almost every type of line fishing.There seem to be millions of shape/size/type combo's. Slipping/fixed, clear/bright, weighted/weightless, fly/bait/lure/ice, glowing/rattling/skipping/balloons, and so on.
One my biggest problems is linking bite to species and timing the hook set right.
Its time to classify FIFA as organized crime.
