Andy Mill's "Virtual Fish Fights"
Tarpon angler and tournament champion Andy Mill uses a pulley system and a bucket of sand to practice putting maximum pressure on his tippets. “When you’re pumping on a fish, you reel down to zero degrees and pull back to 30 degrees. If the rod passes 90 degrees, you’re resting the fish, and you’re in the high-sticking zone where the rod is most liable to break.” Terry Gibson in Florida Sportsman.
