Guys, you are working on the old rules. That wording has already changed. I was on that WP and I challenged trying to find wholes in any way I could, including curved, canted, and else with cads ,examples etc.

Andrew G along Greg were the native english spoken on that group.

The only wording they wanted to add was limiting lenght to 140cm. Just check last minutes , I think the new wording is there. Will check and re post.
