I'm totally impressed by not only your obvious concern, but your stick-to-it-ness in following through with this situation that seems to be a bit of a moral dilema within your church. Kudos to you!
I'm SHOCKED if the leaders truly have less that a year's experience (and that's the average?!). One step that could be taken right away, is for the elders to start a rotation where one Scouter has always been there longer and has 'trained' the newer adult ... in other words, stagger their terms of serving. Not the end-all, that's for sure, but a first step while research
