Connor Henson said 5.14c for Empath on bolts but bit harder placing gear rather than bolts so maybe 5.14d for the gear ascent.
Ondra said BV would be very solid 9a if bolted and placing gear makes it physically a bit harder. Sounds like it's a very strong contender for the hardest trad route in the world. Particularly since JP has done tribe and AO Dawn Wall (aren't the hardest pitches on Dawn Wall pretty much bolt lines?).
