Tubes now account for as many if not more fish each season than do traditional single hook flies. During the early season when the water is cold, tubes offer the fly fisherman a lure/streamer large enough to tempt what can be very dour fish.
Using A Tube Fly
To tie the fly onto the end of your leader, simply pull the hook from the rear of the plastic tube, tie the hook to your leader and re-insert the hook into the tube. If the hook becomes damaged it can be easily replaced without disposing the fly. If you have problems of the hook inserting itself up the tube thread on a bead at the rear of the tube just in front of the hook eye. Always have spare hooks with you!.
Lighter tubes of nylon, in slow or medium flowing rivers, tends to flutter very attractively as it swings across the current mimicking the natural movement of bait fish or a shrimp. Use a fast sinking line to get the fly down to the required depth. It makes the fly swim more naturally. In deep water on lakes and reservoirs the copper weighted tubes come into their own realm. Watch the Local Regulations!
When using a tube fly for fishing you can use floating flylines intermediate or sinking flylines according to the water conditions.
Beware Regulations About Weighted Tubes
There is one disadvantage with using tubes. It is nothing to do with the effectiveness of the fly at catching fish but more to do with the wording of local fishing regulations. An example of this is that in America, Washington State a fly based on a tube is defined as a lure and not a fly under their State regulations and therefore can not be used on fly only water. Their regulations define a fly as 'a lure on which thread, feathers, hackle, or yarn cover a minimum of half of the hook shank of the hook'. We only sell plastic tubes. The regulations in Eastern Canada forbid the use of 'weighted flies' for Atlantic Salmon. Metal tubes are considered 'Weighted flies'. Consult your local fishing regulations before using tubes to see if they are so narrow minded as those of Washington State.
