How tricky is tricky? I'm interested in those edges, but have found few people who know about them. Write privately or answer here so all can hear, but I'd really love to know more. I've found 3 or 4 varieties and plan to cross them back and forth until I have a stable edge, but would love some pointers if anyone has experience with them. Thanks.
