Seriously getting into crawling! Probably...

So my LHS is building a crawler course and I'm so freaking excited. I need some help though. I'm not sure whether to go with 1.9 or 2.2 but I'm thinking a Losi MRC. I think it would be good but post any suggestions down below. I will look up every single crawler you post. Thanks!

1.9 looks more scale than 2.2, but 2.2 can go on more terrain.

Ok. They have just started building the course so when people start running on it I'll see what they are going to run.
