Random, it's easy to get distracted with all the materials we have available, but like flytire said, it's not difficult to tie something specific if you know what you want to tie.
I love experimenting & when I sit down, often don't know what I'll tie. But, when I have a pattern in mind, that's what I tie.
Just lay out the necessary materials for buggers, and nothing else. Then tie only buggers. Discipline yourself man!
Darn it man, don't make me come up there & flog you with a calftail!
