A few tips for the buzzbait:
If throwing towards the bank, hit the bank or right at it. I've seen folks throw towards the bank and are 2-3' short, no hits. It makes a difference!
Throwing to logs, etc- throw well beyond and bring it to the log. Once at the log, kill it for a second or do a quick half spin of the reel to make the blade lift/kick water. Will usually cause the reaction strike with the change in cadence.
Cadence- don't just throw and reel the same speed, Change it up, fast, slow, stop and let it sink a few inches. The change in retrieve drives them crazy. I try to think of a buzzbait as a creature that fell in the water, can't swim well, and is trying to get away from a predator.
