The heavier Seagaur stuff is not very good. It has terrible knot strength. Just got off a 3 day off-shore trip. Captain basically told us that he would rather see us use straight mono than a Seaguar leader. Several used it anyway and they broke off at the knots with every hook-up. I used Yo-zuri and had no problems. We did use some double leaders on Bluefins and that held up fine. The single leaders all broke.
