I found most piles by having low expectations and choosing a certain small area of the lake i thought there would be structure and fishing every square foot. Now if no crappie on one pile, i move to the other. I have quite a few spots on wateree now i fish from march to october-november, in the winter i fish deep water. If you try a spot with no crappie move to the next. Last weekend was strange, i fished everywhere but shallow and struck out. Come to find out i shouldve fish shallower based on a report i got. For longlining or trolling, usually .8-1.2 mph is ideal. Tightlining is great for fishing brush, many times i have to get right into the branches, which means snags and retieing hooks. Thats why i will use a hook, splitshot, and minnow to limit the cost. I also order the hooks in bulk off ebay as i lose alot.
