We have installed numerous PVC attractors on Pickwick lake with great success. They are located near creek channel drops just like our wood attractors. We use an H pattern for beds that we plan on vertical jigging. For trolling we drop them in a straight line along the top of the drop parallel to deep water. Usually give them at least one month before fishing. They have to be in the correct depth for the time of the year you are fishing. But like wood structers I have installed some that does not produce very well (reason unkown). The only way for me to locate them is with a GPS. If you do not have one I suggest you should think about getting one. Hope this helps.
