I purchased a Super Trees starter kit from Scenic Express the other day and finally got around to putting a few together for the layout.  Below are before and after shots of an area just east of the Mississippi River bridge.  Here are a couple of my first impressions of the resulting trees.
- The trees are pretty fragile. Definitely a "last thing to add" detail.  It will be interesting to see how they hold up over time.
- They are taller than the woodland scenic trees. The added height looks more prototypical to me.  The kit instructions recommended 7 inches for N scale.  These are about 5 inches.
- They seem to be more detailed.  They don't look near as foamy as the Woodland Scenic trees.  They may be a bit too wispy.  
- They have a very irregular shape, which I think helps them look more realistic.
- They are very easy to build and take only a few minutes for each tree, although drying time seems to be an overnight deal.
I'll probably add a few more thoughts as I add more trees.  The kit yields about 30 trees, so I'll be adding more and taking additional pictures as I go along.
What do you think?  Woodland Scenic s hardwood tree kits or Super Trees from Scenic Express?
