"Mister Speaker, Point of Order"
When a tyer sits in front of his vice, the temptation to be tying non-stop is strong. If a roomful of tyers are cranking out flies, it's hard to learn from each other, which is the point.
So take turns. One tyer is "at bat," and should talk about what he's doing as he does it. Others can be tying if they prefer, but it's smarter for the rest to sit on their hands while they watch, listen, and learn.
