I could see them fish also being counted as your limit for that day also if you are transporting them. How would a warden know that they are not from that day and you are grind the evidence to head back out and double dip. Just a theory.
10/2 PP for me with a 2 foot mono leader. I like not having stretch in my line and when I get snagged up I only break the mono and don't leave 20 feet of mono in the river to piss me off at a later date when I snag it.
