Dipping is probably the best if youre IN the timber. Casting and retrieving can be effective along the edges. Longlining and spider rigging works well too if you can stay out of the timber. It has been several years back but I used to really enjoy my 10' dipping pole with me sitting on the front of the boat running the trolling motor and even sculling the boat some from tree to tree dipping with minnows under a slip float.
Health nuts are going to feel stupid someday, lying in hospitals dying of nothing.
