I recently visited Frankenjura in Germany to do some sport climbing with some newcomers to rock climbing. I have made a short video about it. Maybe this could give you some inspiration should you find yourself in Frankenjura.
no prussik while rappelling? J/K. looks like a super fun place.
Actually, I think Martin is holding the prussic while he rappels, but probably you cannot see it in the short sequence. It's been a while since the trip, so I really cannot remember, haha! Anyone on er personal note, I always use prussic - also when rappelling off single pitch routes.
