If some of you are also fly fishermen does " match the hatch " ring a bell. While some swear by realistic size , color pattern and on and on. One of the most successful flies ever tied is the Royal Coachman. Yet this fly does not resemble any known insect.
I like the approach previously mentioned throw something at them until they bite. if it resembles something in the lake or looks like bozo the clown the final most important thing. Are you or have you caught fish on it ? At the age of 61 I have learned one constant for fishing. Never assume you KNOW what the fish want on any given day. Let the fish tell you by their interest or lack thereof.
Sometimes we fishermen like professional baseball players go into a slump and we start thinking too much. See the ball hit the ball solves the slump. In our palance find the fish catch the fish. I have learned I don't care why they clobber something. I just keep tossing until I find something they will clobber.
