First ley shares the first, ~8B/+ part, up to the small rest, with the more famous First round, first minute, 9b, and then goes left into the last part of the Ley innata, which you follow to the top. This part is roughly 8a, so you shouldn't really fall once you've done the first part.

This Mateusz second of the grade after Papi chulo, which he climbed last year.
