When I was guiding, (saltwater, double hook leaders) I tied 1000 4/0 30 lbs. leaders. Every spring usually while watching a basketball game I would tie between 40-50 per game. I liked to have this done before I arrived in May at the resort so that I didn't have to tie at night after a 10 hour day on the water. I can only speak for myself and most of the other 24 guides I worked with, but most of us would not let others tie our leaders, just personal preference.
