Re: Testing after Shodan
If you don't want to go test, then don't.
If you really want to, then go right ahead. Have you either had routines to challenge yourself, or someone with a higher rank and/or more experience to challenge you? Sounds like you have been spending a lot of time at the dojo training and teaching, especially if you have done that for years, then go for it. If teaching is your thing, then getting higher ranks I think can potentially allow you to teach more to your students in the future.
