In today's episode, Will, Michael, and Quinn climb Will’s Tension Board 1 playlist , “V8B”, to determine whether they are in “V13 (8B) shape”.
The “V8B” playlist includes 6 boulders (4 V8’s, 1 v7, and 1 V9) -- all of which are extremely hard for their given grade. Will primarily uses the V8B playlist as a personal strength metric -- he has determined that if he is able to send all 6 boulders on the first try, he's in “V13 shape”.
