We were in Bonne Terre in June of last year. The dive leaders were excellent, but the safety diver following was AOW and had just
hired on the weekend before. Our group had 14 divers on the first trail, which I thought was too many for two leaders and a safety diver. The first trails were as described, well lit and open to the surface except for a couple of short swim-throughs. The trip up and down the stairs was quite strenuous, especially the first and last time when you are toting all your gear.
Both our leader and safety diver were full cave divers and fully equipped. We had a husband-wife team and the wife was leading and the husband was the safety diver. Both were very capable and skilled. We had a group of 8, which seemed enough.
The "guides" told us that in order to lead the tours, a full cave diver had to do the trails countless times over months and be able to navigate them flawlessly before ever being allowed to lead groups. They didn't say what the requirements were for the safety diver, but since our safety diver was a full cave diver, I didn't question it. AOW doesn't sound right, though to be a safety diver. That may explain why they had 3 leaders in your group, besides more customers - maybe in case of splitting. On one of our dives, one of the divers suddenly wanted to leave and the safety diver signalled the leader and he and that diver left together and went back. This left us with only the leader in front. My buddy (an instructor) and I were at the back.
There were a couple of short swim-throughs and we were told in advance that we could either go through if we were comfortable or around.
The trips up and down those stairs were big ones. It was also cold and clammy in the mine. I was wearing a wetsuit and never warmed up between dives. My visit was before they got a heated room or whatever they have now, so it must be more pleasant now.
