Hawkeye, and Roop,
I wrote about it back sometime last fall when I had a flyline break on a large striper. I questioned a couple of the line manufacturers. The line breakage is between 30, and 35 lbs. This is why one wants to fish bluewater with a leader which is between 16, and 20 lbs. with either wire, or 60 to 80 lb tippet. Lefty Kreh has an excellent chapter in his books on leaders.
