but as for directissima...you have to place one piece on the traverse...just one...
Well, I think that's a matter of taste. I think I placed three pieces on the traverse. Because they're small active pieces, I simply didn't trust one to hold me if I fell, so I place two early on, and then as I was getting near the end, I place another to protect the finish of the traverse. And frankly, I got pumped silly, hung, and just made a general embarrassment of myself. My second time on it, I think I placed the same gear, but worked out the feet much more carefully, and got to the end with arms to spare.
As for what the rating should be, that's beyond me to say.
