Owen, a quick note on sizing: I'm a bit over 5'10", and my Raven 565S is perfect for me with drop bars.
I did consider a Nomad X590M, which has a lower stepover height and longer chainstays. That model is robust, if a bit lighter than the Nomad. In the end, I opted for the lighter and versatile Raven.
I do most of my riding on tarmac, though the Raven is a sturdy bike, and handles gravel, logging roads and the like very well. I weigh rather more than you (85 kg), but the Raven seems unfussed by that :-)
Good luck, and enjoy your search -- and even more, the bike you find! You've come to a good place to search for bikes & ask for advice.
