I actually have a couple lengths of line made from the running line of a WF4F line that I use. The hand lining while fishing from a kayak is my main concern. Plus you can only fish a part of the cast as you stated. When You have a line near the same length as the rod you can fish the whole length of the cast. When bank fishing the longer line also becomes a pain to cast since it is a fixed length. The only experience I have is fishing with the Amago, when it comes to Tenkara. I figured I could use another rod or two as back ups or to let the wife use when she decides to come fishing with me.
