Just out of curiousity how long are you playing out the bass? And are you keeping tension on the line at all times? First and foremost is your drag set right? I don't know the specific ratio to line breakage, I go by feel, but I've noticed that I lose fish when I give any slack to them. I also like to put my rod down in the water when reeling in so that the fish can't jump as easily.
I like a sweeping hookset with cranks, a snap up with jigs, and with plastics I like to go the opposite direction of the fish on the hookset. I am not the most experianced, but these tactics work for me.
