Fish smaller spots. Not just around a brush pile, but in it, on the shady side, over it or wherever the fish are holding that day. When I'm fishing something like a brushpile or a ledge, I make an effort to fish small spots around the size of a basketball. Crappie can be finicky, and even 3 or 4 inches away from the magic spot can cut way down on what you catch. Up your boat control and casting so you are putting your bait not just next to something, but right next to it and on the side you want.
I outfished a guy 10-1 or worse one time. The fish were on the shady side of standing trees, and you almost had to have the bait touching the tree to get bit. He was flinging it out there close to the tree, but I was putting it on the tree.
Also, wash your hands with soap after you put sunscreen or bug spray on or handle gas or oil. Seen this burn a lot of folks over the years. The real tip though is to carry the disposable nitrile gloves in the boat so if you have to put sunscreen or bug spray on or mess with gas or oil on the water you don't get the smell on your hands. No need to wash because you don't get it on your hands to start with.
