Half Life was first climbed by Felix Knaub a while back and it didn’t get a repeat for a long time. After getting more into bouldering this spring I could do the second ascent of it a few months ago. Felix proposed 8C back then, and I think the way he climbed it was for sure hard 8C. After finding slightly different beta and by using a kneepad it for sure made it a bit easier. Might still be 8C though. Hard to say, as its a rather long boulder problem with about 25 moves.
