Well looking at the trunk of the Auran "Tree Conifers" they look very much like sugar pines, at least the bark is pretty close, the pine cones not so much.

Height is a little short at only 60 meters.
I'll stick a flock of them up at the top of the incline and see what they look like.
BTW this whole discussion is kinda leading me to think that the whole new Tnext thing might actually be a good thing. I can not see myself participating in large projects due to my undependable health but for touching up a preexisting route with a group, could be fun.
Edit, I went ahead and did a group of the Auran conifers and also did all dmdrake's Sugar Pines. Turns out Auran's trees are only a paltry 40 meter tall.

here are some screenies

Auran's too bad the pine cones look like giant pears

all dmdrake's from the short side

All dmdrakes's from the tall side. Note the Auran trees don't look too bad from a distance.
The color on the Auran trees is kinda light, both trunk and foliage, IMO.
Edit: mcguirel is not able/willing to work on Sugar Pines atm
