Safir has this job in his blood, he was born to do this, he was able to manage the group and employ a lot of strength despite walking as well. I understand very well the responsibility and mental energy you have to put into the circles to lead them at their best, and he was able to do all this perfectly.
Giovanni ditto, he is great as a leader, safe and focused, attentive to everyone and always available and organized to help someone with the movements if they had difficulties.
