He had done the route many times before, so the challenge of climbing it without the bolts was mostly mental and to figure out how place the gear:
The problem was to link a few meters above the last protection and just before the last crux. You need to place a cam down below in a hold where you needed to grab before and make a dynamic move.
He also said that he unfortunately couldn't remove the glued bolts, but that he actually didn't even think about clipping one.
Jernej is still(?) best known as a competition climber but is also an extremely accomplished allround climber with ~8C, 9a+ DWS, 9a sport, 8b+ multi pitch and now 8b+ trad under his belt.
Last week he reached the semi final in the European Lead Championships and 7 July he's competing in the Lead World cup at Villars-sur-Ollon.
