Welcome to the (relatively) silent world (though you do notice lots of other sounds - wondered what the hell it was 1st time I heard air moving about in my wing
).
Back to novice-hood but with a nicer learning curve, also I don't think that buoyancy is as hard to master with rebreathers with smaller loop volumes (I believe that that applies to the Meg as well as the Kiss) - I had a try-dive on a YBOD and buoyancy seemed much harder than with the Kiss I eventually bought.
Have fun!
