Trav grades creates confusion and should be avoided

Traverse grades use a difficulty scale in between routes and boulders. The logic behind this is that traverses are often quite long making them hard to compare with boulders. On the other hand, it is impossible to draw the line when a "traverse" is long and horizontal enough to be graded softer than a boulder. This creates confusion and also that sometimes a horizontal 8A is harder than an 8B. In the 8a scorecard, we advice climbers to always record also traverses with personal boulder grades and leave the traverse grade as a comment. A solution for topos and for the Fontainebleau, where most of the traverse grades boulders are found, is to identify traverses by marking them 8Aa.
