Catt is spot on about negative clues, anything. And I'll repeat ANYTHING thats negative will deter a hit, and that goes whether its clear water or not. I smother my lures with the proper scents, to mask the human scent, I use light green mono line, (although flourocarbon should be used) Im used to the mono's and very rarely do I exceed 12 pound test.
The point about cadence is important because that is often what attracts a fish to a lure. If your cadence of twitch, twitch, RIP,.is what attracted the follow, continue it. When the fish gets close, pay close attention to how it reacts to your lure. If you feel a faster movement will entice a strike, as if you think the bass will think the prey is scared, try it. If that works,.. great. If it doesnt work, stick to the original cadence and see what happens then. Its a game of "what do I need to do"
The fish's reaction could be of territory, impulse, hunger, or even competition.,.. within all of these, scent, sight, vibration, and sound will be what triggers the initial reaction, if that sense is negatively altered, the fish will swim away,..But If you can produce a positive que to the correct sense, the fish will be more likely to strike.
Using the clear water can actually be your friend in this way. So be very attentive to the fish's reaction, in whatever you do, or even use for that matter. A jerkbait offers many different looks and sounds. This may be why it was more effective than other lures that day. If you are returning to the same lake? Id use the same lure that produced before, covered in a scent that matches what the lure looks like. and watch what happens, then mimic what works everytime you see one coming for a follow.
Good Luck, I hope this helps some
