I recently made a post on several sites concurrent with this one (Rockstar section) about coiled sighter construction. I did this to make sure I receive credit for these design ideas. The coiled sighter design methods are exclusively my own and have greatly benefited TPO members, including Aaron.
Sometimes I feel like I don't get the credit I deserve for doing all that work and spending all that money on monofilament!
This is the same reason one might write an article about a specific fly pattern, when it is perceived that others may be copying it.
I don't see the harm in doing this. Since this is an open forum without remuneration for user-contributed content, I don't think that TPO "owns" any of the intellectual property.
