USA national bouldering champion, Paul Robinson and two of his good friends, Matt and Charlotte Bosley,  have visited the other days Natural High Climbing Gym. "Amazing!" kept saying the enthusiast american, determined to come back in Brasov. He was attracted to all of the blocks, but he mostly liked the 50 degrees inclined panel on which he put up a few difficult problems. These problems remain a challenge even for the best climbers in Brasov. (One of the problems from the three that Paul put up was send by George Maris).

The three americans created boulder problems that represent a standard for rating harder problems.
