Hey Carl - thanks for the message and sorry for the delay in getting back to you.

BIG fan of Obsidian here. I use it for all of my notes - from training courses to Home Insurance summaries!

As for the messenger, it's great. if I had one wish it was that the strap was a little longer. Knomo also seemed to have stopped making them (they've been "Out of Stock" for over a year now) which kind of surprises me.

So I'm going to try out a Sling bag from Alpakka for the first time. I'll be sure to write up my thoughts!
