You can define "strong" any way you like. But for me a "strong lineage" would be authentic, verifiable, and credible. If it's not fit for public discussion then it is what it is, but it's not strong.
So dismiss me. Fine by me. I would even strongly encourage you to, Cliff. Stick with someone proven....by lineage.
After all Takeda Sokaku didn't have one either. Why he didn't even have a black belt!!
These things are important to a lot of people Cliff. Be careful out there.
