If you are going through a lot of hooks, your sinker is too heavy.
It is a trade off in terms of line strength. The heavier you go the less fish you will catch. The lighter you go, the more fish you will hook but you'll lose the big ones.
Look through the iso fishing videos on youtube. I fish with those guys often, as we don't usually go over 20lb leaders. I personally fish with 8-10lb leaders for drummer.
