Hello creekman. I fish a lot of creek and river situations here in northern Michigan and use similar tackle. I use a 6 1/2 foot and a 4 1/2 foot ultralight most often. Both of these are rigged with Ultralight reels and 4 or 2 pound test monofilament. I have no problem casting 1/64oz jigs with out bobbers so your situation should be fine for casting. I also use 13ft, 16ft and 20ft, telescoping poles with various line sizes, depending on the situation. I prefer to use the spinning outfits if I am dipping around the brush as it is easier to control the amount of line you need out, but the shorter poles require being closer to the structure. The 6 1/2 to 10ft rods work great for dipping in brush, especially if the water is clear and you need to stay back a bit to keep from being detected.
It is not about the equipment you have to use,
It is about how you use the equipment you have. :D
