This is a very long circuit by ValveJob. It has a very good mix of mtm and cart models. There are many custom textures and some custom models as well. Racing is great with a wide track surface, but it also has plenty of twists and turns to keep you on your toes. The only problems with this track are some of the models could have been better placed and some of the textures don't line up quite right. But, those are minor things. I definitely will be running this track many times.
