HLA-B27

Sit-start from broken left crimp on arete and small sharp crimp on the right. Getting myself to the smooth crimp groove was definitely the crux and ended up being all about the foot work; toe-hook on the right and a powerful kneedrop made all the difference between impossible (with my finger strength) and not-that-fingery. A bit morpho beta, probably, but you maybe can also sit-start of you are shorter with a more crimpy beta.
