Berkley Fireline 4 pound might fit your criteria. Stiffer than other braids when new because it's fused, so it rarely gets wind knots and doesn't require a leader. Stronger than it's rated line strength, so it can handle your big Redears. The FishN'Fool knot works great for tying braid to a lure. It's just a Uni knot with two passes through the hook eye instead of one. The Varivas braids are the best, but i wouldn't use one without a leader. They are the most expensive, but a lot cheaper if your buying a reel on Digitaka! Double Cross is my favorite. Handles and sinks better because it's a braid/ester hybrid line.
