In my son's old troop the SPL, ASPL, Troop Guide and Patrol Leaders are all elected. They recently went to more than one ASPL because the SPL and the ASPL often had conflicts attending an event and to offer more opportunties for leadership to make rank. I thought both reasons were bad. That troop registered 65 boys, had about 35 show up at meetings (except on the day of elections then almost everyone was there) and about 10-15 on monthly events.
