I share the opinion of the most other reviews of this hook, but I've found the TMC 300 to be the only hook to tie the Vladi Worm. Its 6X length and strength make it the ideal choice. The Vladi Worm can be a difficult tie because of the need to heat and bend the shape of the hook as well as dealing with the latex material. But a slight, careful heat treatment doesn't seem to affect its strength. However, I would shy away from using it to tie the Wooly Bugger because of its extra length.
