I'm fairly new to backmount doubles (I prefer to dive sidemount doubles). During the portions of the dives that we're in open water (in the basin or the spring run), I can maintain decent trim and buoyancy management. At this point, I'd probably feel comfortable doing wreck dives to 80-90 feet. I would want to accrue additional experience before going deeper.
Buoyancy in the cave is slightly more complicated because I'm in the early stages of learning to navigate flow. By the end of the course, I will have completed about 20-24 supervised dives in doubles.
(Further note: I may or may not reach Full Cave in this time period. If I only make it to Apprentice and need additional practice or extra innings, I've already accepted it as a possibility).
Edited to further add: Reggie does offer a Doubles Orientation to divers who either want to take it or need to take it before moving into the cavern. Based on his assessment of my skills on Day 1, he decided that I could progress.
