An idea of floating tubefly I did have several years ago, so this is not a new flytype, just developing old idea.
First I made tubeflies floating by choosing materials lighter than water, but soon I wanted the tube float in bad water conditions, so I have to do something about it.
Since I started developing my dry salmon fly ďPomperoĒ I had all kinds of different ideas how to make a fly float. I take some of those ideas back and started to develop some of them. This led to solution for my floating tubefly. After testing this idea in real flyfishing I realised itís better than I thought. I noticed that fly is capable rising back to surface after pulling it under water by sank flyline or other reason. Then I believed that this type of fly is capable to float longer fishing periods without chancing it to new one after a while.
But next question is why my tubefly should float?
The next pleasent way to fish salmon is after dry fly fishing is fish with fly in water surfase, not underneath it. I have found that tybe fly is best type of fly to do so. On the other hand, ordinary flyies does too but their capability to stay on the surface is not too good and thats way they donít fill the number one rule in succesful fishing, fly must stay on surfase and not to sink.
My floating tube is made of three different size of silicone tubes. Inner tube is smallest (dia) and in the both ends there is pieces of little larger tybes (2-3 mm) which are melted to smaller tube ends. Over all this is placed little more bigger tube (heat shrinking) which is melted and shringed to the ends of tube. In the other end I leave 6-7 mm extra for hook. If you doubt the waterproof of the joints, you can add little glue between tubes. Usually the joints are so tight that water donít enter to the space between tubes. While tying the fly you can tight the joint areas more with tying line.
The air between tube layers floats the fly nicely, expecially when it is well greased and used with small hook.
The fly itself is tyed like ordinary tybefly. I like to ty the wing as one piece 2/3 round the body. If I put wing top of the tube, I use body hackle. Clear tube is specially good when fly is made to imitate small fish.
So how the fishing is done with this flytype.
There is many different ways, but the similar factory is the flies lightness and ability rise to the surface in end of the cast.
First the usual way I fish with this fly. I use floating line with long taper with two reasons. I like to cast with long taper in my underarm cast and with my way the fly comes from upstream head down the fish will see the line first. Long taper will give a little time for fish to calm down before the fly itself shows up. The fly must leave little wave to the surface when taking in.
The movement is made by rod or by pulling the line. By using combineisons of these two you can make variable rhythm to the fly. When fishing this way the cast should be directed upstream or at least across it.
The other way to fish is with fast sinking line. When you pull the line the fly dives towards bottom, but when you donít pull it will rise to the surface.
Both ways have worked with salmon and trout with me. You always can do it between these two or some other way. Compearing to the ordinary wet fly fishing the flies wont stuck to the bottom so often because light fly will swim little over the bottom even when we pull it lightly. This way this fly is more useable tubefly than others.
I warmly recommend.
