My son became a Den Chief last September when his brother joined Tigers. I'm the den leader, so I felt if he wanted to be a Den Chief why not in my den. He really enjoys it and plan to stay with the boys until they cross over into Boy Scouts. He serve 4 months not to long ago as a PL because he was the only first class in his patrol that was able to be PL and hated every minute of it. During that time he remained a den chief and helped within the den. The boys look up to him.
At Day Camp last summer, my son went with the den and they all had a good time. Since he is the only Den Chief in the Pack right now, all the other boys enjoyed him too. I had a mother come up to me after day Camp was over and thank me for such a nice Boy Scout. Her son was going to quit scouts after camp, but after meeting my son and talking about scouts, he decided to stay on.
Den Chiefs (good ones) hold an important part in the Pack. They set an example of what scouts are suppose to be and encourage the Cubs to crossover into Boy Scouts.
That's my two cents worth!!
