Jacopo Larcher does the world's hardest trad?

Jacopo Larcher, who three years ago did La Rambla 9a+, has done his hardest route ever. "I have never invested so much time in a route before. Anyway, I decided not to grade it ;)" The Italian found it six years ago and the last year the 25 meter line in Cadarese, Italy, has been his big focus. He says that he has worked on it during possibly 50 sessions or more. In regards placing the gear, Jacopo says it is not so hard to place. "It just makes it more pumpy between the two hard sections." (c) Paolo Sartoro Photo It is a well known fact that trad grades are harder than sport grades. One reason for this is that in the beginning of the sport era, you had to place the quick draws as you were climbing as you had to place the trad gear. Later, the sport ethics changed towards pre-placed quick draws. Further more, it seems that at the same time we have seen grade inflation for sport routes there has been deflation for trad. Currently there exist some four 8c+ trad routes meaning that there possibly should be a two grades gap comparing it to sport routes. Understanding that the gear placement did not have so much impact on the difficulty for Larcher, it just might have been 9a+ or 9b with bolts. So what do you think? Did Jacopo do the first 9a trad route in the world?
