At this point I don't see a lot of benefit of it vs says peak performance buoyancy. Not all of us like kool-aid.
You might have a different opinion about "kool-aid" and/or your gear set up when you've done some more diving. Then again you might not, however, at 0-24 dives you won't know what is the most appropriate and comfortable gear for yourself so try to keep your mind open at this stage. Also I doubt I would compare Fundies with Peak Performance Buoyancy. I've seen relatively new divers who've done one or the other and those that have done PPB don't even compare as a general rule.
I can see the primary hose and even the fin if the kicks can't be done easily with splits. IMO air sharing drills should be done using the gear you are actually going to dive with.
Actually I think air sharing drills should be done with as many types of setups you can get your hands on. That way you can figure out what is the easiest method for yourself.
