I would go with the rusty considering what you said you want to use it for. It is a durable truck that can drive through grass and all that stuff. You can also order aluminum parts for it from
www.rdracingproducts.com The jato on the other hand has better speed but on the Jato you lose the chance of going through grass adn stuff like that. To me I think they made the Jato a bit too low. Just my opinion!
