If you are on a good weed bed that you know are holding fish don't cast in the middle of that bed.
Work your way in , it keeps you from spooking fish by snags.
Throw a small spinner bait.
A small jig on a slip Cork , set at the depth a foot above the snags.
Repeat the first three as you work your way in.
After you have done all this use a small jig and work your way in the weed bed.
Always use line that can bend the hook . Not snap the line.
Line snapping above water sounds like a bb gun , under water a 22 .
Time to go for it , after you have done all this. Put on the heavy jig and go for it always working your way in.Good luck to ya...
