Weather was
awful!
I was on the way to work so I had 1/2 hour on the TR (grey) and about 20 minutes on the AM. The 'local woods' turned out to be a pretty big area of forest land complete with fire roads and singletracks; more than enough to get a feel of the bike.

TR
I'm 5' 9" with 29" inside leg and the medium is spot on. TBH I'd be happy with either bike; the TR is marginally more compliant at the back so there's a bit more grip on roots etc with the same tyre, but this may just be down to different tyre pressure.

AM
What a fantastic, confidence-inspiring bike! I say
bike rather than
bikes because they're essentially the same- the AM is optimised for a slightly longer travel fork, so with a degree or so slacker head angle the top tube feels slightly shorter which felt slightly more natural for me. That, and the fact that the extra travel might give me a bit more confidence at trail centres, means I'll probably choose the AM, but like I said, there's very little in it.
This is my colour!
