And when you do cast them try and have something similar in weight to the streamers you plan to throw on the end. If you are planning to throw heavy streamers a 6 wt is a bit light for smooth casting. If you are planning on using a long sink tip or a full sinking line a 6 wt is a bit light for lifting the line and fly out of the water. If this rod is mainly for tossing streamers and sinking lines then you might want to up size a bit.
