The rock at Stena Kotlu is very specific, as almost no one is climbing there. There is a boulder immediately after the 1st protection, crimp on the right side of two distinct holes makes it easier. In the corner, below the 2nd one, the route keeps pushing you, and you only get a good rest on the big hold more to the right. In the final difficult section, above the 2nd protection, there is a good hold in the middle, but difficult to spot on the first go. Definitely harder than 7+!
