Tube fly tying is a new facet of fly tying I want to explore. The basics are in this kit.
I am sure there are better kits out there but I imagine they are more expensive. I think if you use up this kit you will have a good idea of what tube fly tying is all about. Also you should be able to figure out if tube fly tying is your thing or not. In the world of fly tying, $30 isn't to expensive. So if you don't care for it you won't be in the hole too deep. Its just a descent kit to get your feet wet.
Only thing I would change is remove a few cones and a few dumbbell eyes and replace them with a half dozen or so brass beads. I think that would make the kit even more complete.
Bottom line if you are curious at all about tube fly tying you can't go wrong with this.
