If you are going lighter than a six wieght I would say forget about multi tip lines or shooting heads and just use a selection of Poly leaders, you will be suprised how deep you can get with a fast sinking poly leader and they are easy to change to suit the depth and current.
If you are fishing heavier rods then the multi tip lines can be an advantage, but they do hinge a little bit and the floaters can be hard to mend at distance.
All the best.
