The leader is a very important part of Tenkara fly fishing. Compared to long lines like traditional fly fishing, Tenkara fly fishing requires line management, which is why design and quality are our first priorities. For our suggestion, you can choose a shorter leader to give more space for your tippet. It will greatly help netting fish, reducing casting difficulties and improving casting accuracy. (For example, starting with a 10ft leader with your 12ft rod) After you are getting used to it, you can choose another length of leader depending on your fishing conditions or personal preferences.
