Hey, no complaining about awesome weather!
Fyi, I'll warn you, I think the Xerces look great, and Fatbike tires do to (though I feel like they come with to many studs by default), but I found no use personally for Nokian Gaaza Extreme's. They had all the disadvantage of fatbike tires - a floaty feel that floats on snow rather than cutting through it to the road, heavy and slow and a lot of work to push, as well as being noisy. At the same time, they're not fat enough to gain the advantages of fat bike tires - the additional snow and ice handling an actual fatbike tire has. They're to fat to gain the advantages skinny tires - cutting through the snow to the road surface, being lighter faster easier and quieter to pedal.
It's just personal opinion I suppose, but I would much rather have the 38c Gravdal's than the 2" (or so) Nokian Extreme's. I had bought a pair of Extreme's and sold them - they seem like they only have niche uses to me.
