9a FA travers by Chris Sharma

"About 30 moves and if I had to put a grade on it I’d say it’s comparable to a 9a route. I know there is a travers rating system but no idea how it works. Anyone know what this could be?" Travers grading is in between the boulder and lead difficulty. A 9a route is more or less the same in difficulty as to do 8B+/C. In other words, Sharma's FA travers could be travers graded 8C/+. On the other hand, 8a has for many years said that it is just confusing to use travers grading as it is impossible to draw a line when a boulder qualifies to be travers graded. 8a use small letters when the difficulty is based on the route grading system and big letters for boulder graded climbs.
