As I've gotten older, I've concluded I've caught plenty of "regular" sized fish of all species.  So about the only thing I've done differently is spend more time fishing for the bigger fish.  As a result, I fish with bigger baits than earlier years.  May not catch as many fish, but I believe the average size is a bit larger.  I have favorite lures and colors, but also switch lures, color and depths when the fishing is slower than I want.
