Yes, I do use scent. Yes, I do like to plan my trip so that I am fishing prime water that is holding bait during the hours of the daily solunar peaks. Those are the best hours to be out at those times of the season anyway. Sometimes it seems that scent and solunar tables work, but I cannot be sure. It could be bait, panfish, ducks, turtles, red wing blackbirds, squirrels or any life whatsoever.
All life favors essentially the same environmental factors.
If anything else is moving around actively feeding, chances are good that bass are doing the same thing. If there's just a flock of sitting ducks with their heads under their wings, it is not a good sign for your fishing success. There are lots of names and many modifications of schemes for the basic solunar tables. I've looked into a few with fancy names and charts. As far as I can tell, the only major difference betweeen most of them is in the fancy name and hype.
