My 2 cents, Bleeding edge sounds interesting but you may have lots of problems. If you care about a having a working machine for general purpose day to day use better settle for a little bit non bleeding edge.
For example, with all my due respect to all, I tried BTRFS, but had problems,
they went away when I reinstalled the poor old Ext4. Please read this Baloo is The Responsible of Unresponsivenes to get an idea what I mean.
Feel free to ask whatever.
