I learned some pretty good brush fishing tactics from watching John one day at Hardy pond. Probably utilized in the south but, because I have never fished down there, I had never seen it done before.
Once I saw it, I didn't even need to ask questions as it made perfect sense to me. Instead of dipping brush and straigh lining your offering (especially when you have limited verticle movement) John was using a small float. I would have never thought of that and it made perfect sense to me after I saw it.
I use this trick all the time now when I am fishing brush piles or downed trees. Especially when branches are exposed above the water and I have to snake my rod up in the middle of them.
