If your not haveing any luck at all, I would make the following adjustments:
Try 4lb mono.
Downsize your lures (3" senkos and tubes, #5 or #7 rapalas, etc.)
When useing spinners, don't use a steady retrieve. Add some rod tip twiches to
make the spinner dart eraticly (also good with rapalas) or reel at a steady
quick rate and suddenly slowing the reel for an instant when the lure is in a
good looking spot. This is a hard tecnique to explain but its been VERY
effective for me. What you want to do is have the spinner move along fairly
quick and steady and suddenly the spinnerbalde slows for two or three
revolutions and then speeds back up again. You dont want the spinner blade to
stop spinning entirely. When done right in close proximity to a fish, it
almost always draws strikes.
