I excel at two things: googling and avoiding spend money.
I won't be buying tyres for a while so will be interested in your critique but I do have my mind set on tubeless...one puncture already this week albeit on skinny thin Kenda Kozmik Lites
Tubeless is a win whatever you do - fewer punctures, can run lower pressure, and you lose the rolling resistance that comes from friction between the tube and tyre. Just remember that for cycling on gravel etc that fat is faster if tyre construction is equal.
Come to think of it, I have links for a lot of this stuff in my evernotes acc:

Tyres can make 25% difference on road, drum testing wrong:

...Just treat all the RR results from drum tests with EXTREME skepticism: Heine's roll tests prove they can be very misleading - and become more so as you move on to rougher surfaces increasing vibration.
These are Heine's thoughts on fork trail:

Otoh, Heine, although he may have won a NASA fellowship, thinks its impossible to make chainstays for a performance bike that will allow tyres wider than 40mm. So he's capable of deep idiocy in defense of his beloved 1950s French style 650b tourer/adventure bikes. So again, skepticism advised!
