I use a stiff 20 lb mono "shock" leader for my pike fishing and I've yet to lose one to a chomped leader. I've caught several in the 10 lb range and many many up to 5 or 6 pounds with absolutely no problem. I have had to change the leader from time to time though.

As for flies, red and white flies tied out of cross-cut bunny strips work great for me.
