Redge usaully to my experience the biggest most aggressive fish will hit first,they call this pecking order I believe. We were fishing brushpiles that were marked by bouys and some that were not marked. We cuaght fish on every pile we fished, we just caught 2-3 keepers at each pile. When the water temps get up in the mid to upper 80's to low 90's the fish will school up better on the piles. Right now they are post spawn just hanging out eating but still in shallow water somewhat! Here is my rule, when its calm with no wind or current I fish wood, when there is wind and current I fish rip rap. That usaully works! EB
