Pretty slick. I really like it. You get a lot of run in a smallish space with some switching fun. It also fit something I wanted in a small layout, an incline to 2nd level with return loop.
I have a thread with a few ideas for a smallish corner layout and two 5x9 layouts. Looks like space will be too tight for the L's but I have expanded the one 5x9 to 6x10 and it will go in a murphy bed style fold up!
