That experience galvanized my intentions to re-work the Foam Trouser Worm to fix some of the issues that have relegated it behind the leather version in my box. I think that this the updated version is a significant improvement.
- Switch to a size 6 Scorpion Gaper hook for more positive hook-ups with zero risk of bending the hook.
- Switch to a single strand of big-fly thread for the tail instead of mono-filament to reduce stiffness of the tail under water.
- Make the end of the tail out of a brass bead. This adds weight to the end of the tail that adds action under water and is also a more durable way to make a stopper for the foam beads.
- The bead at the end of the tail and the heavier gauge Scorpion Gaper hook both add weight. Replace the tungsten bead at the hook-eye with a brass bead to offset this inrease in weight.
Here are the tying instructions for the new and improved Foam Trouser Worm. There is a little bathtub footage at the end to show how the new fly acts in the water.
