Wilson, what species is this? It looks like the subalpine fir (abies lasiocarpa) we see in Alberta and BC. The trunks are smoother than our spruces, and the needles are flatter and more dull. I know some people use them as bonsai, but I'd love to see how it goes with these, as there is not a lot of information out there aside from there having trouble adjusting to lower altitudes and otherwise being similar to spruce. I'd like to know if you find this to be the case, if that's what they are. Now that I look at it "the fatty" looks like a very healthy spruce. With that trunk base and backbuding, you should be able to make something very impressive in a relatively short period. The firs should make very naturalistic forest/shohin/bunjin too, depending what your thing is. Long post I know. Nice stuff.
