Ive only caught one in the 8lb class, but several 7lb, and lots of 6lbers and here is my technique...
After the hook set, I keep firm pressure on the line, this includes the rod tip being bent. Part of landing a big bass, is having pressure on the rod tip, as well as the line, so that you can "steer" her to wherever you want. It is common to get really excited and reel as fast as you can, but this is not the best technique, unless she is already swimming at you. Many big bass will wrap themselves around cover that is near by to try and free themselves. At this point it is VERY important to keep the rod loaded and tight line as to not allow them to free themselves.
If you can feel the bass coming up, like they are going to jump, keep pressure on the line, and the rod tip bent, but lower the rod tip, as to not have upward pressure. Many times this will result in a splash and tussle at the top, but not allowing them to jump out of the water. Many times bass, or any fish, are lost when they jump out of the water, because it allows slack in the line.
Remember big fish don't get big by being stupid and getting caught.
I always call a fish that jumps "educated"
